Files for Setup of a FALCOM A2D GSM modem to an Omron CJ1M-cpu22 to send SMS text messages. Included files are CX-Prgrammer File and Word Doc explaining the Setup.

Modscan will emulate a Modbus Master enabling you to check modbus communications with a Slave.

CS/CJ1 Communications Protocols Reference Manual

This set of files contains the CX-Protocol file and PLC code for a CJ1 PLC and serial card to communicate to the ZX Laser sensor and F160 vision system. This was achieved with a serial card and CX-Protocol. The commincations that this sensor uses is Comp

This sample program will allow you to use the standard inputs namely inputs 000.03000.04000.05 as single ended inputs high speed counters. Note the maximum speed on these inputs will be 2kHz. These will count independantly of the scan time.
Why did

This little gem of a program will calculate the FCS (Frame check sum) for a given string....an invaluable tool when diagnosing and debugging Hostlink communication sequences with an Omron PLC...

This program will display the clock time and date on a screen and allow an operator to easily adjust the time/date values though the familar use of thumb wheel switches.
The screen used was an Omron NT21 and the PLC is the Omron CJ1M.

Omron CX-Simulator V1.3 Operation Manual for Software(WS02-SIMC1-E)
CX-Simulator is a PLC simulaiton package for Omron PLC's. Can be used in conjunction with CX-Programmer CX-Supervisor CX-Server Lite CX-Server OPC.

Generates a Pseudo random number using the mixed congrential method.
Formula r(i+1) = (a r + b) MOD N
This will generate a random number between 0 & N-1 with N = 2 (pwr 20) = 1048576 a = 1909 b = 221571
The MOD operation is the integer

This program illustrates how to simply Toggle a bit on or off with a single input. (A basic flip flop if u like)
Two versions are provided
The first version will work in a CJ1 / CS1 PLC because of the direct diff funciton on the input bit.
