I have barcode data in a string data table in my SLC5/05 from a laser engraver (ST) and I need to compare it to barcode data in a ASCII data table (A) from a Cognex camera. I tried to bring the camera data directly into a ST register but no luck (all the Cognex examples show ascii registers). I would like to move the 15 characters (could be changed to 16) from the ascii table to the string table so I can compare the two. Any suggestions?

I can't wait to hear how to trigger the camera via Ethernet!! Too bad my project had to ship with the hardware trigger. Now if I can do job changes via Ethernet I'll have a great package for my next project.

The ML1100 supports ST adress type but the message command doesn't support using it with a PLC5 write. I get the message "local address may only be ST file type 485CIF Write Command" & Target doesn't support this address type. I haven't tried the 485CIF Write instead of PLC5 Write in the MSG configuration. Cognex needs a SE8 command to trigger the camera. Banner has predefined address for trigger - Cognex does not. (that I've found). I hardwired a plc output to the trigger on the breakout board (so much for only running power and ethernet to the camera)

I've had to goto a hardwire trigger for the camera since the ML1100 doesn't support ST address in a message command (need to send "SE8" to camera). For job change I'm going to output the part number BDC to a robot and let it communicate the part number to the camera serially. I may use the bigger IO board in the future so I can select the job directly.

Does anyone have examples of a A-B Micrologix1100 connected to a Cognex 5100 via Ethernet? I've seen the examples for SLCs but the ML has different commands. I'm trying to get pass/fail, camera busy, and part angle signals back to my plc.

I'm using a 2711-T5A15L1 with a 2711-NC13 cable to a 1764-24BWA with 1764-LRP processor. I got rid of the error by deleting EVERYTHING but one pushbutton. One error I found was my alarm messages triggers weren't defined for each alarm (last tab). Fixed that in my original application BUT I must still have another bad address. The hunt continues...

After downloading PLC code (ML1500) and PV application (PV550) for the first time I have the error "683 File Access Error" on my PanelView Screen. I made a quick scan on Goggle and found that I probably have the PanelView trying to read a data-table that isn't in the PLC. (I get the same error if the PanelView is disconnected from the ML1500) I'm going to write a small PV application and test communication and then start adding screens and alarms back in. Any suggestion of a quicker solution to my problem?

Does anyone have RSlogix5000 tagname standards that they could post?

That is the correct cable. You'll have to configure RSLinx on your PC to match the ML1500 (DF1 out of the box).
