K bits/s Screened double twisted pair Configuration Number of devices 8 devices maximum (1) 55 datalink addresses (one device can occupy several addresses) () Length of bus Tap links 1000 m maximum excluding tap links 0 m maximum Services UNI-TE Maximum message size TSX/PMX model 40 TSX 17-0 TSX 47-0/5 TSX Nano TSX Micro/Premium Terminal port PCMCIA card Terminal port 18 bytes bytes bytes 18 bytes 40 bytes 18 bytes Point-to-point requests with confirmation (question/response) initiated by any connected device Unsolicited point-to-point data, without confirmation, initiated by any connected device Broadcast messages initiated by the master device Other functions Transparent communication, via the master, with any device in an X-WAY architecture Diagnostics, debugging, adjustment and programming of PLCs Security Monitoring Check character on each frame, acknowledgement and repetition of messages, if required, ensures transmission security Bus status table, transmission error counters and device status can be accessed by program in each device Bus status and devices connected from the master PLC (except for TSX Nano) can be accessed from SYSDIAG software on an FTX 417/517 terminal or PC compatible (1) devices maximum with TSX Nano/Master PLC. () 5 datalink addresses with TSX Nano/Master PLC. Note : Some devices have application, network and datalink layers which are compatible with the UNI-TELWAY communication architecture, but do not have a standard physical interface (limited data rate, remote power supply, etc). Performance BCT (ms) The cycle time depends on the : i Number of devices polled (datalink addresses) i Data rate i Turnaround time of each device i Number, length and type of message BCT = Bus Cycle Time, is the interval time between two polls to the same device = 9.6 K bits/s = 19. K bits/s The above curve gives the UNI-TELWAY cycle time as a function of the number of slaves at 9.6 K bits/s or 19. K bits/s, with a typical turnaround time of 5 ms per device (excluding messages). 470/ Te

2 Characteristics, devices which can be connected pages 470/6 and 470/7 The following table shows the time to be added (in ms) to obtain the true BCT value as a function of the traffic (N = Number of usable characters) : Time (ms) Exchanges 9.6 K bits/s 19. K bits/s Master to slave N (1) N (1) Slave to master N (1) N (1) Slave to slave N (1) N (1) (1) N = Number of usable characters corresponding to the messages to be exchanged. In a distributed control system architecture, the application-to-application response time not only depends on the communication system, but also on : i The processing times of the message source and destination devices i The degree of asynchronism between the bus and processor cycle times Event Confirmation This response time must be evaluated by the designer of each application according to the devices which are connected. Device 1 CT1 TC1 CT1 CT1 The processing time of a device may vary from one to two cycle times depending on the degree of asynchronism. BCT BCT Device CT CT Action BCT = cycle time. CT1 = Device 1 bus cycle time. CT = Device bus cycle time. Devices which can be connected TSX/PMX model 40 PLCs TSX/PMX PLCs can be connected to the master or slave in a number of ways : 1 Via integral link The and PLC processor are linked by connecting a TSX CSD 100/00 cable to a TSX LES 64/74 cable connector. The cable is connected to the bus via a TSX SCA 50 T-junction box. Via TSX SCM 1i6 module These modules have a UNI-TELWAY interface on channel 1. 1 Channel 0 has the following interface, depending on the version : i RS C for the TSX SCM 116 module i Current loop for the TSX SCM 16 module i RS 485 C for the TSX SCM 146 module The module is connected to the using a TSX SCA 6 subscriber socket and a TSX CSB 015 cable. When it is connected in this way, the processor (or module) operates without having to be sent a configuration, and regardless of the status of the PLC (RUN-STOP). TSX 7 modular PLCs, Master or Slave, can be both Server and Client at the same time : i Server, the PLC is server for its system functions. i Client, the PLC is client for its application program.

TSX Micro and TSX Premium PLCs TSX Micro and TSX Premium PLCs can be connected to the in one of three ways : Via integral processor port The AUX port (8-way mini-din type) has a non-isolated RS 485 serial link channel (maximum distance 10 m). The maximum distance can be increased to 1000 m using TSX P ACC 01 T-junction box. Via integral TSX SCY 1600 module port This module for the TSX Premium PLC has a multiprotocol (including UNI-TELWAY) Half-duplex isolated RS 485 serial link channel. TSX Micro TSX Premium Via TSX SCP 114 PCMCIA card A slot on the processor and on the TSX SCY 1600 module receives among others the multiprotocol (including UNI-TELWAY) isolated RS 485/RS 4 PCMCIA card.
