C200H help

[Buckaroo 0]

So this is an extension of this topic from a few days ago: http://forums.mrplc.com/index.php?showtopic=21421 The machine manufacture sent me CX-Programmer with a couple of cables. I installed the software and used their instructions to do the following setup. In the software I started a new project and made the following changes under the CHANGE PLC box: I set the device to C200H and the CPU type to CPU 03. I was instructed to turn SW3 and SW4 on the Host Line Unit to 0 to set the baud to 19200. SW1 is 0 and SW2 is 1 to set the node to 1. Back in the CHANGE PLC box I leave the NETWORK TYPE as sysmac way and under the SETTINGS tab set the Host Link Unit number to 1 and then under the DRIVER tab set the baud to 19200 and Comm port to 1. Navigate back to the main window, click on the PLC tab and then WORK ONLINE. I get an error saying something about not being able to connect to the PLC. I try a couple or more times and then swithc to the other cable and after trying numerous times it finally connects to the PLC. I transfer the program and scroll down throught the logic while online. All of a sudden I get a communication error and now no matter what I do, the computer will not connect to the PLC. Any ideas as to what is going on with this? Also the reason for all this is because a couple of weeks ago the PLC had the ERROR LED lit and I am trying to determine why. The machine currently will run with no issues but we are concerned we have not found the reason for the ERROR LED being on and want to figure out why so it does not come back to bite us later. Any suggestions or ideas will be greatly appereciated. Thanks Tom

The normal setup for the front mounted rotary switches should be: SW0: 0 SW1: 1 (Node 1) SW2: 5 (9600) or 6 (19,200) SW3: 2 (Programming Level 2) Back of the host link: SW3: On (1:N Protocol) Hoping the Error Light is Off, because the PLC shouldn't Run with the Error Light On

Jay, Thank you for helping me with this. I was relying on information from the machine builder and they told me they have since quit using Omron so maybe their support for this is out of practice. The machine did not run when the Error LED was lit. It has been running fine for a week now with no other instances of the error. I would like to figure out though what casued the error so we can limit any down time in the future. When you say SW3 on the back of the Host Link unit I am asuming I have to remove the unit to access right? If so can I do this with power on or would it be better to power down first? Also once I get connected is there some sort of fault log to be able to look back at? If not then I will have to wait for the problem to arise again. Thanks for your help. Tom

Ok so I am making progress. I verified all switch settings and BINGO was able to connect to the PLC. I transfered the program from the PLC and see on the left side there is an ERROR LOG with a small red X. I see that this indicates that the error logging is disabled. So now I am trying to determine how to set this up. According to help file I should be able to check the LOG Enable. This option seems to already be checked as enabled but is "grayed" out so you can no do anything with it. Any ideas on how to get this set up to log errors? I will also continue to read through manuals to and figure out. Again thanks for all the help. Tom

Sorry. C200H-CPU03 does not support error logging. You are talking about an original C200H. Circa 1985.

Jay, Sorry it took me a few days to get back to the forum. Enjoying a long weekend, now back to work. Thanks for helping me on this. I see now I will have to be prepared for if/when this error happens again. Tom
