Micrologix 1100 unit with an 1762-OF4 analog output card. The card is configured for a 4-20mA / scaled for pid. It gets a scaled value of 0-16383 in the program to determine its output. The problem is that it the output is 0-21mA instead of 4-20mA. In the manual it says that normal range is 4-20 and full range is 0-21. The manual says, "The over- or under-range flag comes on when the normal operating range (over/under) is exceeded. The module continues to convert the analog output up to the maximum full scale range."
What causes the module to enter this condition? Any ideas on our problem?
