Indramat CLM Control
The CLM control comes in three flavors. The 1.2 is the basic control, without removable firmware. The 1.3 has more options, and has removable firmware with the program held by a battery. The 1.4 is the latest and last version of the CLM, and has some improvements in both the firmware and control. See the pictures below for identification

The Indramat CLM 1.3 is easily distinguished from the 1.2 by the removable Firmware/Program module just below the keypad on the right. This is where the firmware number can be found. This model uses a battery. Have you changed your battery lately?
