17 Guidance Cabling.8 Cabling.8. Cable routing 0 VAC supply lines and signal lines must be laid in separate cables at least 0 cm apart. Even within the switching cabinet, it is advisable to leave space between power and signal lines. Digital signal / bus lines and analogue signal / sensor lines should be laid in separate cables It is advisable to use shielded cables for analogue signal lines. The shield should be earthed at the entry or exit to the switching cabinet. The shields should be as short as possible and of the largest possible cross-section. The central earthing point should be > 0 mm² and connected to the PE ground wire by the shortest route The shield is generally connected to one side of the switching cabinet only, unless there is a potential equalization with significantly lower resistance than the shield resistance Inductivities installed in the same switching cabinet, e.g. contactor coils, should be provided with suitable suppressors (RC elements) Switching cabinet components with high field intensity, e.g. transformers or frequency inverters, should be shielded with separator plates with a good ground connection. Surge protection for long distances or external lines Where lines are laid outside the building, or over longer distances, suitable surge protection measures should be applied. For bus lines in particular, these measures are essential. With lines laid outside, the shield must have adequate current-carrying capacity and be earthed at both ends. The surge conductors should be installed at the input to the switching cabinet. -

Recommendations: Immediately before touching the electronic circuits, briefly touch the metal housing of the PGU connection. It is safer to use an anti-static wrist band, connected to the Minus of the system. No changes (e.g. plugging/unplugging jumpers or I/O modules) should be made with the power switched on. -7

25 PCS hardware CPU overview.. Hardware and firmware versions for PCS The firmware versions for the PCS are generally backwards-compatible in terms of hardware, so old CPUs can be fitted with new firmware, in order to take advantage of new functions. This feature is highly valued, and we will try to retain it for as long as possible; however, we cannot guarantee this. Firmware update 6 kbyte flash as memory The firmware can be updated locally at any time using PG via the PGU interface. This is done with the «Saia PCD FW Downloader» function on the «Tools» menu in PG. If the connection is lost during the download, or the power fails, the Saia PCD will start up in a special «boot» mode, in which the procedure via PGU can be repeated at any time.

32 PCS hardware PCS memory ranges.9 PCS memory ranges The PCS units have MB of flash EPROM as user memory. This can be freely partitioned by the user with the PG programming tool into program memory (default 008 kb) and memory for text/data blocks (default 896 kb). 896 kb RAM as memory for historical data The user can then edit and archive large volumes of historical data (text/data blocks ). As the data can be read over network or telecommunications lines, parent systems are also able to archive, analyse and display data graphically, and run energy management processes..9. Example of a memory configuration The screenshots below show an example hardware configuration and matching software settings in PG for a PCS with 0 kb flash (hardware version <= 00) and a PCS with 008 kb flash (hardware version > 00). Extension memory is configured automatically and is used to store RAM text and data blocks. Step : Hardware configuration Hardware versions to 00 Hardware versions from 00 There are only 8 kb of flash EPROM available for code/text memory. One block of memory is lost to configuration data (header), because flash EPROM can only be accessed in block mode. -

34 PCS hardware PCS memory ranges.9. Partitioning options for user memory In the PG hardware configuration, the user memory is partitioned by default into lines of code and texts/dbs, in a way that suits most applications. In the case of a large program with few texts/dbs or a very small program with many texts/dbs, the user can partition the memory manually. In order to choose an appropriate breakdown, the following should be noted: the partitioning is into "kb lines of code" and "kb text/dbs", where the "kb lines of code" can only be changed in kb steps, as every line of code occupies bytes the result of the formula ( "kb program cells") + "kb texts/dbs" must equal the effectively available user memory, e.g. kb + kb = 8 kb each character of a text occupies byte each -bit element of a DB occupies eight bytes in the address range , and the header of the DB takes up a further three bytes Example of manual partitioning of a PCS: Hardware versions to 00 Hardware versions from 00-7

35 PCS hardware Data storage in case of power failure.0 Data storage in case of power failure The resources (registers, flags, timers, counters etc), and possibly the user program and the text strings/dbs, are stored in RAM. To ensure that these are not lost in the event of a power failure and that the hardware clock continues to run, the PCSs are fitted with a buffer capacitor (SuperCap). The RAM data is always buffered with the SuperCap, but the buffering of the hardware clock can be disabled, increasing the buffer time for the RAM. CPU type Buffer Buffer time PCS Super Cap (soldered)... days ) ) Depending on the ambient temperature; the higher the temperature, the shorter the buffer time. If the hardware clock is disabled, the buffer time increases by approx. days To retain the data in RAM at least volts are needed. This voltage is reached after approx. 6 minutes, but this level is sufficient only for very short-term data storage. The complete loading cycle for the SuperCap requires at least minutes ( tau). -8

38 PCS hardware Monitoring the CPU (watchdog). Monitoring the CPU (watchdog) The watchdog monitoring unit can be used to monitor the correct processing of the user program with a high level of reliability. In the event of errors, effective safety measures can be triggered, e.g. to switch off parts of the installation... Software watchdog for PCS The hardware watchdog provides maximum security. However, for non-critical applications, a software watchdog may be sufficient, whereby the processor monitors itself and the CPU is restarted in the event of a malfunction or a loop. The core of the software watchdog is the instruction SYSWR K 000. When this is first issued, the software watchdog function is activated. This instruction must then be issued at least every 00 ms, or the watchdog will trigger and restart the controller. Instruction: SYSWR K 000 ; Software watchdog instruction x = 0 x = x = R/K x ; Parameters as per table below: ; K constant or value in register The software watchdog is deactivated The software watchdog is activated; if the instruction is not repeated within 00 ms, there will be a cold start The software watchdog is activated; if the instruction is not repeated within 00 ms, XOB 0 will be called and then there will be a cold start XOB 0 calls are entered in the PCS history as follows: "XOB 0 WDOG START" where XOB 0 has been invoked by the software watchdog "XOB 0 START EXEC" where XOB 0 has been invoked because of a supply fault -

39 PCS hardware Internal LED and graphic display. Internal LED and graphic display The PCS has a programmable three-colour LED (CPU LED). Outputs / communication interfaces can be used to connect external displays and terminals to all PCSs. On the PCS.Cxx0 and PCS.Cxx types, there is a graphic display... CPU LED With the three-colour LED (red/green/yellow) built into the cover of the casing, the system integrator can show the user the current status of the controller at a glance.

42 PCS hardware Storing data in EEPROM. Storing data in EEPROM On the PCS, an EEPROM is used to store configuration data. Part of this is available to the user to store -bit values (EEPROM register). These values are not lost even in the case of battery failure or an empty buffer capacitor. On PCSs with hardware version < E, there are five EEPROM registers (addresses 000 to 00). On PCSs with hardware version E, there are fifty (addresses 000 to 09). The EEPROM registers are independent of the "normal" registers with the same addresses. The values are read with a SYSRD instruction and written with a SYSWR instruction: Read: SYSRD Kx or R x R y ; Kx is the address of the EEPROM ; register in range K 000 to ; K 00 for PCS CPUs, ; or K 000 to K 09 for PCS CPUs ; Alternatively, the address of a ; register can be passed across, ; containing the address of the ; EEPROM (same ranges as for ; K constants) ; R y is the target register Write: SYSWR Kx or R x R y ; Kx is the address of the EEPROM ; register in range K 000 to ; K 00 for PCS CPUs, ; or K 000 to K 09 for PCS CPUs ; Alternatively, the address of a ; register can be passed across, ; containing the address of the ; EEPROM (same ranges as for ; K constants) ; R y is the source register When using the instruction SYSWR K 0xx, note the following: The EEPROM can be written to a maximum of 00,000 times, so it is not permissible to invoke the instruction in a cyclical manner or at short intervals. The processing time for the instruction is approx. 0 ms. For this reason, the instruction must not be invoked in XOB 0 (XOB for a power failure) or during time-critical processes. -

43 PCS hardware Manual/emergency operation. Manual/emergency operation The provision of a manual/emergency operation level allows the user to intervene in the process at any time in case of emergency or service. The PCS has an integrated connection level with a total of 8 relay outputs. Four of these are set up as make contacts and four as change-over switches, so the user can interlock the outputs in the case of a two-stage fan control (see connection diagram, section..). The switches have auto/off/on functions. Four more switches and potentiometers are used for manual/emergency operation of the analogue outputs. This allows e.g. fans or baffles to be overridden. The switches have auto/man functions, and the potentiometers can be set from 0 to 00%. The plates provided can be used to label system-specific manual/emergency settings. The inputs/outputs are described in more detail in Chapter. -6

44 PCS hardware Use of Port #0 (PGU) as RS- interface.6 Use of Port #0 (PGU) as RS- interface A new function was introduced with fimware version 0A. This allows PGU Port #0 (Sub-D, 9-pole) to be used as a free port (e.g. Serial S-Bus, MC etc.). This allows the user to use the PCS as a gateway (Port #0 as 'slave' port). Port #0 on the PCS is used for modem access and by the PGU connection. The Port can be switched using the following system commands: Instruction: SYSWR K 900 ; PGU Switch instruction x = 0 x = K x Default setting: ; Parameter according to table below, K ; constants Port #0 used for the internal modem Port #0 attached to the Sub-D connector, the internal modem can no longer be used The user program can issue the instructions to switch from modem to Sub-D connector at any time. If the instruction is issued during communication, this will be interrupted. The value is saved in the buffered area of RAM, i.e. it will be retained even when the system is rebooted. The port can also be switched directly from the Online Debugger. For this, the PCS first has to be stopped, then the following instruction has to be input: I SYSWR K 900, K 0 <enter> switches Port #0 to the internal modem I SYSWR K 900, K <enter> switches Port #0 to the Sub-D connector The DSR signal (Pin 6) from the D-Sub connector is used to detect the PGU cable (i.e. to recognise that the cable is connected). When the signal DSR detects a logical ("high"), Port #0 will be run as a PGU port and earlier configurations will be deactivated. "PGU Switch" FBox/PCS In the standard library in sub-directory "Special functions" is the "PGU Switch" FBox. This FBox in the FUPLA program allows Port #0 (PGU connector) to be used as an RS- interface also. -7

45 Communication interfaces Serial data ports PCS Communication interfaces. Serial data ports The PCS controllers support the protocols to connect various peripheral devices such as printers, user terminals, light and shade and access control systems. The connection is made via standard interfaces such as RS-/RS-/RS-8 at up to 8. kbit/s. The PCS supports the following modes: MC mode = character mode to connect external systems with ASCII protocols (e.g. EIB, M-Bus, Modbus etc.) S-Bus mode = for exchanging data with SBC systems in a network in half-duplex operation IMPORTANT: - Port #0: on the PCS is used for modem access and by the PGU connection. The modem channel is active in normal operation. When the connection to the programming device is established with the PGU cable, the DSR signal switches the port to the PGU connection (PGU has priority and works by default at 8. kbit/s). When the PGU cable is removed, modem access is re-initialised. With SYSWR K 900 (K), Port 0 can also be switched to the PGU D-Sub connector, and so can be used as a normal interface (e.g. SBC S-Bus) - Port #: The PCS does not support all handshake signals from the PCD7.F0 communication module that are required for modem operation (see above). - Port #: External RS- connection, on PCS.Cx/Cx without internal display only Port #0 and Port # are handled by a UART. A UART cannot support ports running at 8. kbit/s at the same time. 8. kbit/s not possible 8. kbit/s and 9. kbit/s not possible either 8. kbit/s and 9.6 kbit/s works 9. kbit/s works -

46 Communication interfaces Network connection / field bus control. Network connection / field bus control Even for more complex or large-scale automation tasks, the excellent network capability of the PCS allows it to be extended almost without any limit. Whether the local data points are implemented with standardised network connections such as LonWorks, EIB, Modbus or M-Bus, or with an economical SBC S-Bus or BELIMO MP-Bus, the extensibility of the controller offers almost limitless possibilities. Example configuration Telecommunication via modem option LonWorks as option Standard SBC S-Bus interface BELIMO MP-Bus via PCD7.F80 module.. LonWorks interface The LonWorks technology is a universal automation concept, which is becoming more and more important in the field of building and industrial automation. Its many advantages such as decentralised intelligence, modular structure and adaptability to existing infrastructures make the LonWorks technology increasing interesting for data transfer in the field. The individual network users, the so-called nodes, can exchange data among themselves on an event-driven basis. LonWorks is the platform for manufacturer-independent communication between different aspects of building automation. The DDC Compact meets these various requirements by virtue of its modular interface design and great flexibility. The LonWorks host interface in the controller allows the user to define more than 000 variables for data interchange with other systems. Its programmability also allows the system integrator to adapt the system to the technical requirements of the building systems. -

47 Communication interfaces Network connection / field bus control FTT-0A transceiver technology For the network connection, SBC uses the industry-standard FTT-0A transceiver technology patented by Echelon, with the following characteristics: Cable type: wires twisted Transmission rate: 78 kbit/s Network structure / cable length: free topology max. 00 m, Bus topology max. 700 m Number of LonWorks nodes: max. 6 per segment, over,000 in a domain Standard network variables SNVT a The implementation of a MIP (microprocessor interface program) allows over 000 SNVTs (standard network variable types) to be defined in a DDC sub-station and linked to other Saia PCDs of external systems. All SNVTs current specified in LonMark are supported by the Saia PCD systems. To connect to LonWorks nodes with proprietary information, "explicit messages" can also be sent. After binding (linking the variables), this information must be backed up using the "Upload DBx" function in Saia PG. Without a backup, this binding information may be lost after program changes and subsequent downloads... MP-Bus interface for BELIMO drives The fields bus was developed by BELIMO specifically for MFT and MFT drives (MFT = multi-function technology). Saia Burgess Controls has developed two switching modules for 8 and 6 drives for integration into the whole DDC-Plus range. An MP-Bus network (MP = multi-point) comprises a three-pole cable connection between the switch in the automation system or control unit and the drives. Up to 8 drives can be connected to a communication channel. Further process data can also be sent to the attached drives directly via a drive or add-on modules on the MP-Bus. Passive sensors, active sensors and -point on/off signals are supported. The direct connection of standard sensors for humidity, temperature etc. to an MFT/ MFT drive makes analogue sensors Bus-compatible. For details, see Technical Information sheet P+P6/. -

48 Communication interfaces Network connection / field bus control.. EIB interface At some point, EIB users reach the performance limits of the EIB components obtainable on the market today. Efficient management of building installations requires powerful functions uniting all aspects. The PCS controllers with associated EIB driver offer an optimum solution for complex EIB tasks. The principle PCS controllers can access the EIB network via the serial RS- port on the EIB interface module. Depending on its user program, the PCS issues instructions over the EIB network and receives constant information from it on the EIB peripherals. This allows logical links, timer and counter functions, mathematical operations or sequential processes to be implemented within the EIB network... M-Bus and Modbus interface The M-Bus (EN -) is an international standard for remote reading of counters. The M-Bus connection is made via a standard RS- interface and an M-Bus converter. This enables amounts of water, heat or energy to be recorded in a DDC sub-station. The measurements are then processed via a component library in SBC FUPLA. The interface to the Modbus is provided by an RS-8 port on the PCS. The Saia PG component library allows the user to read and work with process data and transfer control values to the Modbus network. This very popular network standard is often used by compact climate control manufacturers to connect to higher-level systems. Detailed information on the M-Bus and Modbus interfaces can be found at: and Other connections You country office will be happy to provide information on other external system connections such as Siemens 96R, Cerberus, GENIbus for Grundfos pumps, STX- Bus for NeoVac, TwiLine or JCI-N-Bus. -

93 Inputs / outputs Manual operation.7 Manual operation Manual/emergency operation of the PCS.Cxx0 and PCS.Cxx devices The provision of a manual/emergency operation level allows the user to intervene in the process at any time in case of emergency or service. The Compact Easy has an integrated connection level with a total of 8 relay outputs. Four of these are set up as make contacts and four as change-over switches, so the user can interlock the outputs in the case of a two-stage fan control (see connection diagram, page 9). The switches have auto/off/on functions. Four more switches and potentiometers are used for manual/emergency operation of the analogue outputs. This allows e.g. fans or baffles to be overridden. The switches have auto/man functions, and the potentiometers can be set from 0 to 00%. The plates provided can be used to label system-specific manual/emergency settings.
