AC 800M IPConfig
Hi,
Currently we are trying to set IP address of AC 800M using IPConfig in Control Builder M ver.6.0 but it did not work. The error message is: "Run-time error '8020': Error reading comm device".
However when we tried to set IP address of AC 800M using IPConfig in Control Builder M ver.5.1 (in another PC), it worked and then we can set the desired IP address for our PLC.
Anyway, when we try to install Control Builder M ver.5.1 in our PC, we could not run IP Config since error message appeared: "Component 'MSCOMM32.OCX' or one of its dependencies not correctly registered: a file is missing or invalid".
We looking forward for advice.
Thank you in advance.

Are you sure your serial driver and device is OK?
Try connecting PuTTY.exe (internet freeware) to the COM port, wire up the AC 800M controller to it (port 4) and then power up the controller.
If the COM port is OK, you should see the controller booting, testing memory, displaying its current IP address, etc. before switching output to the internal log.
No output = wrong COM port or problem with your serial hardware/driver.
I have successfully taken the IPConfig.exe from an SV5.1 installation and run it on a standalone Windows 7 PC without any other ABB software loaded.
Don't mix ABB version 5.1 SW with Windows 8, likewise, dont mix ABB version 6.0 SW with Windows 7. Each version is built for one or a few target operating systems.
If you know the IP address of your controller (see PuTTY.exe above) you can change it following this alternate procedure:
1. Set computer NIC with an IP alias on the same subnet as the controller's current IP address. Connect AC 800M to the same network. Verify connectivity with ping.
2. Create controller in CBM. Set *desired* IP address on Ethernet port 1 and 2.
3. Set *current* IP address at Controller name -> Properties -> System Identity
4. Go online with download
5. Reset controller
6. Now, the controller should have taken the address(es) set in step 2.
7. Remove IP alias from NIC
8. Update Remote System Identity in project to new IP address.

Hi,
The number of subscriptions is only used for the alarm and event connection.
It is possible to check the number of used connections and subscribing systems, using the "System Diagnostics" FB-interaction window/Advanced/Alarm Event.
You will most probably find that only the remaining subscribers are connected.
On the other hand, leaving the "Max no of subscribers" on a higher value than 2 will not be a problem.

Hello,
you need to obtain MSCOMM32.ocx and place on your PC.
Then run the following commands with an elevated command prompt (right click and run as administrator):
cd \windows\syswow64
regsvr32 c:\MSCOMM32.OCX (this is the path of the file on your PC)
You should now be able to run the IPConfig Tool on that PC.
If you have a node it works on, try to find the MSCOMM32.ocx file in C:/Windows/SysWOW64.

Hello,
Please place the mscomm32.ocx file in c:/temp and run the command prompt shown below. Please run a command prompt as an administrator. I fixed this exact issue by doing this.
Thanks,
Mike
