The definition of Module Status Data for IC694MDL660


In GFK2314D, the description for 16 bit Module Status data of IC694MDL660 is as following:

Bit 1~9 for Internal use
Bit 10 Module I/O Data: 1=ready. 0= not ready
Bit 11 Terminal Block Present: 1=TB not present, 0=TB present
Bit 12~16 not used.

Why is Bit 10 set to 0 and the module works well and is providing the correct input data to CPU.


GFK2314D currently specifies the meaning for bit 10 to be “Module I/O Data: 1-ready, 0-not ready”. This is true ONLY for version “A” of the module (IC694MDL660A).

For versions “-AB” and “-BC” (IC694MDL660-AB, IC694MDL660-BC) the meaning of this bit should be “Firmware Update Mode: 1 = module waiting for firmware update".
