Posted 21 Mar 2023 Hello, I was ale to connect the Power Supply (IC693PWR321) and CPU (IC693CPU311) however, I'm unable to go online. I have attached files so you can see what is happening: Match serial communication setup for PC and PLC PC, used Device Manager to set up COM4, 19200, 8, odd, 1 PLC, used CPU under hardware set 19200, 8, odd, 1, (see attachment PLC communication setup) connected and disconnected serial/USB cable and port appears and disappears in Ports (Com & LPT) in device manager Setup Hardware in PLC PLC, defined hardware and pulled report (see attachment Hardware BOM report) Why ( 2 ) IC693CPU311 ? Redundant processor not an option in CPU 311. PLC, disable password under CPU (see attachment PLC communication setup) Setup Target 1 Make target active, Clean Build, Validate (see attachment Validation error message) Go ONLINE, received time out error 8503 (see attachment Time Out Error) Pulled HELP for Validation error Highlighted line in Feedback window and looked in Companion window for help response. (see attachment for Help 1 & Help 2 for Validation error) Could be that the drivers are not available for this old hardware????!!! Share this post Link to post Share on other sites
Posted 21 Mar 2023 Are you using the proper GE cable? The ports on these processors are not RS-232. (I'm traveling and do not have that cable with me, but it has electronics in one end.) Share this post Link to post Share on other sites
Posted 21 Mar 2023 It is possible that the latest version of the PAC Machine Edition software from Emerson is incapable of communications with the old CPU311. That particular model has been out of production for several years. But I would not put that as the most likely possibility. As pturmel notes, the details of your cable connection are important. The port on the power supply is RS485, while the majority of USB/serial converters are USB/RS232. Please tell us what you are using. Also, in the navigator panel, right click on the "Target1" and open up the properties window. Scroll down to the "Physical Port" item and make sure the selected COM port number matches the COM port assigned to your USB/serial converter. Quote Why ( 2 ) IC693CPU311 ? That's just a quirk of the software. The first instance of the part number is in the field for the backplane. In your case, you have a model that includes the CPU in the backplane instead of as a separate module. Share this post Link to post Share on other sites
Posted 24 Mar 2023 Sorry for the delayed response, I had my family arrive for a few days' visit. Regarding the cable, I did not purchase a generic cable. Got the cable made for the 90_30 PLC. I wanted to avoid compatibility issues by purchasing a cable made specifically for this PLC. I knew the PC and PLC serial communication parameters must match. So, I checked, rechecked, and checked again the following serial communication parameters: PC Device Manager / Ports (COM & LPT) / USB-Serial CH340 Com Port: COM 4 Device Manager / Ports (COM & LPT) / USB-Serial CH340 (COM 4) / Port Settings Bits per second: 19200 Parity: odd Stop bits 1 Data bits: 8 and matches, PLC PAC Machine Edition / Navigator / Target 1 / Properties / Inspector Physical post: COM4 PAC Machine Edition / Navigator / Hardware Configuration / Main Rack / CPU (IC693CPU311) expanded (double click): Data rate: 19200 Parity: odd Stop Bits: 1 Checksum Words: 8 So, how do get the programming software to communicate with this PLC? My thoughts are: Hardware compatibility issue - Direction, switch to older PC hardware and transfer programming software to it. Software/driver issue - Direction, switch to older version of programming software. If so, what version is compatible with this old PLC hardware? Please give comments for the best direction in your opinion or propose another direction of action. Please see attached the cable IC690USB901 Thank you!

Posted 26 Mar 2023 One other possibility: Are you running PAC Machine Edition in a virtual machine? Sometimes the COM port number assigned in the VM does not match the COM port number assigned by the host machine. If there are any LEDs on you USB/serial adapter, watch them while you are trying to establish communications. Any occasional blink of one of them indicates an attempt to communicate with no response. No LED activity indicates a mismatch between the port Machine Edition is using and the port used by the converter. Share this post Link to post Share on other sites
Posted 5 Apr 2023 (edited) PAC Machine edition 9.8 is not running in a virtual machine.
