2 Channel Digital Input Modules
750-400, -401, -405, -406, -410, -411, -412, -427, -438, (and all variations),
753-400, -401, -405, -406, -410, -411, -412, -427
For the digital inputs the object 0x6000 (also 0x2000 possible) is used.
2 Channel Digital Input Modules with Diagnostics
750-419, -421, -424, -425, 753-421, -424, -425
Bit 7
For the digital inputs the object 0x6000 (also 0x2000 possible) is used.
2 Channel Digital Input Module with Diagnostics and Output Process
Data
750-418, 753-418
The 750-418, 753-418 digital input module supplies a diagnostic and ac-
knowledge bit for each input channel. If a fault condition occurs, the diagnos-
tic bit is set. After the fault condition is cleared, an acknowledge bit must be
set to re-activate the input. The diagnostic data and input data bit is mapped in
the Input Process Image, while the acknowledge bit is in the Output Process
Image.
For the digital inputs the object 0x6000 (also 0x2000 possible) is used.
Bit 7
For the digital outputs the object 0x6200 (also 0x2100 possible) is used.
