S5-095U PC connection to occupied SI1 port

3 posts in this topic

I am new to S5, and have been trying to find info about how I can connect a pc to an SI1 port on S5-095U plc where the SI1 port is already being used to communicate to OP15 operator interface. I have read most of the manuals available, but can not find anything close to explanation. I have the RS232/TTY cable and S5 software. Any help would be appreciated.

Hi, If you don't have a second interface connector (located close to the analog inputs connector) there's no solution except to unplug the OP15 cable... JC

JC, thanks for this...I did not know if it would be that simple, or if the use of OP15 unit meant the port would no longer respond to PC interface. The last thing I wanted to do was damage a running machine with obsolete controls. Thanks again.
