4 Installation Installation This driver addendum is additional to the PLC-ANALYZER pro handbook and explains particularities and provides important information for the use of the following driver: GE Fanuc Series 90 / VersaMax / Nano / Micro - programming interface (SNP) This driver makes possible the acquisition of PLC signals through the programming interface of the PLC. It is important, that you read through the driver addendum first, before you use a PLC driver. Please pay attention to the WARNINGS that advise you on possible dangers when using PLC- ANALYZER pro.! WARNING Errors that may occur in the automated facility endangering humans or causing large-scale material damage must be prevented by additional external precautions. These precautions (e.g. independent limit monitors, mechanical interlocks) must guarantee a safe operation even in the case of dangerous errors. 1.1 Installation of PLC driver You can install the PLC driver when PLC-ANALYZER pro is running. Select PLC driver in the menu Extras. In the window PLC driver click the button Add. If the desired driver is not in the list, then you have to install a new driver by activation via the License-Key management (see user manual PLC-ANALYZER pro 5 - chapter 2-2 Installation) Installing additional hardware If you have already connected your programming unit (or your PC) with a serial cable (RS-485) for programming the Fanuc PLC, then you normally must do nothing else. Otherwise connect a free COM port (serial connection) of your programming unit (or PC) via RS422/485 converter with the PG interface of the automation device Installing additional software No software is required in addition to the PLC-ANALYZER pro basic module and the PLC driver.

5 Installation Configuration of PLC driver After installing the driver you can change important parameters under Properties. If you have loaded several drivers, you can set the properties for each driver individually. Fig. 1-1 Configuration of the PLC driver First enter a meaningful name. Then select under Port the COM port from the PC, where the connection cable is connected with the PLC. Set under Baudrate, Databits, Stopbits and Parity the parameters for the serial connection between PC and PLC. The parameters have to agree with the attitudes of the PLC. If the PC is connected with more than one PLC, please set the SNP ID of the CPU you want to communicate with. Otherwise you omit this entry. Use Time stamp to decide whether a time stamp is to be entered in the signal file at each monitoring point or only when the signal changes. In the first case the signal file resulting is bigger because time stamping is continuous even if the signal does not alter. Scan interval lays down the interval between reading data from the PLC. For time insensitive applications e.g. temperatures a generous probe interval can be chosen. The signal files resulting is smaller. Under Symbolism you can assign a symbol file to the loaded driver. This makes possible the use of symbolic addresses during the address input (s. user manual PLC-ANALYZER pro 5 - chapter 4.1 Address selection). In addition to the absolute address the symbolic address and the comment of the address will be displayed and saved in the project and in the signal file.! Note The higher the data transmission rate, the higher is the temporal resolution of the recorded data. To recommend is baudrate

6 Data acquisition Data acquisition 2.1 Supported PLC Models and CPUs The following models of the GE Fanuc-family are supported: Fanuc series CPU 731, 732, 771, 772, 780, 781, 782, 788, 789, 914 und 924. Fanuc series CPU 311, 321, 313, 323, 331, 341, 351 und 352. VersaMax, VersaMax Nano und VersaMax Micro Not listed automation instruments and CPUs of the GE Fanuc-family are normally compatible, but not explicitely tested for it. 2.2 Possible PLC addresses Types of address The following table shows the addresses possible and the appropriate syntax: Syntax Address type Example %Ix Input bit %I0001 %Ox Output bit x %O0123 %Tx Temporary value x %T00014 %Fx Flag x %F00454 %SAx SA-Flag bit x %SA00112 %SBx SB-Flag bit x %SB00432 %SCx SC-Flag bit x %SC00119 %Sx System bit x %S00921 %Gx Global flag x %G00221 %Rx Register x %R00234 %AIx Analog Input x %AI00124 %AOx Analog Output x %AO00003 Table 2-1 Adress syntax GE Fanuc

7 Data acquisition Number of simultaneously recordable addresses Up to 100 addresses can be recorded. An address is a bit- or word address. 2.3 Timing behaviour and particularities during data acquisition The intervals between scan transfers from the Fanuc-PLC to the computer depend on the speed of the data transfer (baudrate), the set min. of transmit data TXD-T1 and the number of recorded signals. With the following formula you can approximately calculate the scan intervals using a baud connection: Scan-distance = 53 ms + 6 TXD-T1 + n 0,5 ms n = number of recorded signal bytes or signal words The following table shows typical approximately scan times for GE Fanuc Series for different transmit data (TXD-T1 = 1 ms): Scandata 9600 Baud Baud 1 bit 111 ms 59 ms 1 word 112 ms 60 ms 20 bit 121 ms 69 ms 20 words 131 ms 79 ms 100 bit 161 ms 109 ms 100 words 211 ms 159 ms Table 2-2 Recording time GE Fanuc Series 90-30
