When I create a new Meter Display object and use a REAL or DINT data type/tag from a PLC, I can not add negative values in the limits.

When creating a New Meter Display Object for a cMT Series HMI, you may not be able to assign a negative value for the minimum or maximum values when using REAL, DINT, or INT signed data types.
Solution: First, select a Local Word (LW) register for the Read Address in the Meter Display Object Properties and set the data type to either 16-bit signed or 32-bit signed. Enter the negative value for the minimum value (and maximum value if required), then change the Read Address back to the PLC tag. The negative values will carry over.
