Multiple PLC connected to CX-S

4 posts in this topic

Hi all Can I connect three CJ1's on Hostlink to a PC running Supervisor? i.e. 1 serial port, converted to RS-422 and three PLC's defined. Thanks

Although I have not tried it myself, it should be just fine. Obviously each PLC needs a unique Host Link number. Also, whatever PLCs you have need to have their 'Default Settings' switch off for the serial port. ie CQM1 DIP Switch 5 = Host Link, 9600, 7, E, 2, Unit 00. As a practice, I typically start at Host Link unit # 01 for mulidrop PLCs. That way if I ever add another, and want to set it up on RS422, it can come into the RS422 as unit 00.
