Problem Statement
This article describes a simple way to add new IODevices for the collection of Misc/PID Tags from AspenWatch Maker.
Solution
To add a new device you can follow the next steps:
1.- You can add a new device on AspenWatch by modifying the CIMIO_LOGICAL_DEVICE.def file located on the following URL:
C:\Program Files (x86)\AspenTech\CIM-IO\etc
if you check the list on AW Maker and compare it to the list on the CIMIO_LOGICAL_DEVICES.def. you will see the available list of devices.
2.- To edit the file follow the next steps:
Save a local copy of the current file. This is done to keep a backup and roll back in case is necessary.
Run as Administrator a Notepad and open the file going to C:\Program Files (x86)\AspenTech\CIM-IO\etc (make sure to change the extension to ALL FILES)
Then you can modify the text file manually, the CIMIO_LOGICAL_DEVICE.def require basically three things on each Column: DEVICE_NAME CIMIO_SERVER CIMIO_DLGP
A Simple way to modify the file is just to copy one of the lines and just modify the DEVICE_NAME for example in this case I will create 5 new devices using the line for IODEVICE1
Then save the file.
Close and Open AWMaker to refresh all changes and this time you should be able to see the new devices.
A couple of additional notes:
1.- Normally you can use the same Server name for all IODEVICES# because they will be pointing to the same CIMIO Server
2.- About the DLGP this case can be different from IODEVICE#. It is worth checking the file and checking if all devices can use the same DLPG or if a new DLPG needs to be created. The IODEVICES normally are split for better handling of the tags network traffic. But if all IODEVICES are running with the same DLGP then only requires adding a new device.
3.- You can test the device before proceeding to use it on AW Maker using the Test API utility
