I'm setting up an Atlas Copco IXB controller using the KEPServerEX release 6.9.572.0 and I'm having an issue activating the two Boolean values for “PVT Comp” and “PVT_MON”. They are reporting false (0) causing Kepware to report null values for these readings (See Below). However, in the web GUI on the Atlas Copco controller tool, I received an accurate Prevailing Torque Compensate reading.
In the Kepware manual, these Boolean values are tied to the “LTR_STRAT_OPT” item, which falls under the last tightening results command set. Specifically, bits 3 (PVT_MON) and 4 (PVT_COMP) need to be turned on. Here is a screenshot from the Kepware manual (page 15):
We believe these bits in Kepware are connected to the mid-values (0060-0063) for the last tightening results from the tool. Below is a screenshot of these mid values from the OP manual (page 5):
Is there a quick fix for turning on these bits that we might have missed?
In the OP manual that you linked to, look at section 2.3 Revision support. In Table 3 it shows the Parameters that are not supported and Strategy options are listed there under MID 61 and 65.
I know the next question is how can you get those values but I have not been able to find a definite answer. My best advice is to connect Atlas Copco because a lot will depend on the model and firmware of the controller. If the firmware is new enough and if the device supports it you might be able to use MID 1201/1202 to get the tightening data and that may include the values you are looking for. Usually if something is not supported it is because that controller doesn't have that information or there is another way of getting what you are looking for. Either way Atlas Copco should know how to get it if it is possible.
Thanks!
