In PAC Control, the Get I/O Unit Quality command should report modules that have a quality code. With this issue, the command does not report modules with quality codes, even if a module has a channel reporting a quality code.
For a temperature input channel, the Calculate and Set Offset/Gain area of memory map does not calculate the correct offset
Knowledge Base - KB89974 - Published:
If your groov EPIC I/O unit is configured for °F, the offset calculation for a temperature input channel is incorrect in two ways: the offset value returned is 5/9ths of the expected value and the...more
For temperature input channel types, offset calibration parameter may cause incorrect adjustment
Knowledge Base - KB89973 - Published:
If you configured a groov EPIC I/O unit for °F and you enter a non-zero value for calibration offset on a channel configured for temperature input, the offset value used in calibration calculations is 9/5ths greater than what you entered.
For temperature input channel types, calibration offset parameter may be applied incorrectly
Knowledge Base - KB89950 - Published:
For groov EPIC I/O units configured with a groov I/O module that reads temperatures, if you set a non-zero value for the calibration offset for a channel and then reset the module or I/O unit, the...more
