Once again I’ve found myself getting just enough info out of an AB manual to get my device working, but not enough to make me happy. I’ve been using the MSG instruction to access explicit information out of VFDs and other devices not available through the project tree and its associated controller tags. Today I used it to set up an 842E-MIP1B Ethernet encoder so I could set my machine zero point. I’ve noticed that for the different times I’ve utilized this instruction the class seems to point to a specific device type and there are other attributes that are specific to the information written to or read from the device.
Does anyone know of an AB manual that lists the different devices and what class number they would be and the list of attributes for each device and what information you are reading and writing? For example the 842E encoder I was working on was device class 23, but if I go by memory, the 525VFD I read parameters from was a device class 93.
It seems the only information available is specific for a certain application in each device manual. While that is great to get me going on that specific instance, I would also like to see the big picture.
Any help would most certainly be appreciated. Thanks all in advance!
