Hello all,
Havent visited in a while. Still trying to learn plcs. I currently work in manufacturing and deal with omron, mitsubishi, AB and Siemens plcs.
I have a question about getting on line with a Micrologix (AB) plc. The micrologix is connected to the main PlC, which is AB RS logix 500, via the 232 connection. There is no other port on the MicroLogix plc. There are a serious of other remote plc bases connected to the main plc, these are on each of the print units. When I run RSlinx, i can connect to the main plc and can see the other remote bases, but i cant see the MIcrologix plc. I cant disconnect the 232 link while the machine is running or the machine will stop (as this is a jam detector PLC). Can anyone shed a bit of light on this?
BTW, I connect to the main plc via a 1785 (i think thats what it is) cable to a PMCK card in the laptop.
So I guess my question is, how do i monitor the Micro plc while they are running. I need to get online with it, and dont know what I need to do to achieve this.
Thanks for reading, hopefully someone can help me out.
Thanks
