TAC Menta Online Device DI block shows Offline for I/O modules with numerical names


  • TAC Menta Online Device DI block shows "Offline" for I/O modules with numerical names
  • The DI block in TAC Menta has a functionality "device offline", when the device name starts with a number (e.g. 2), the device online function doesn't work as supposed.
  • Device online flag is tripped, (or actually set to 0) but will never be reset when device is online again.

The reason that this functionality doesn't work is because if the device address starts with a number it's considered to be an I/O module.


Rename the I/O module devices to a name that does not start with a number.
