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
The input modules seize 2 Instances in Class (0x65).
2 Channel Digital Input Modules with Diagnostics
750-419, -421, -424, -425, 753-421, -424, -425
The input modules seize 4 Instances in Class (0x65).
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
acknowledge bit for each input channel. If a fault condition occurs, the
diagnostic 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.
The input modules seize 4 Instances in Class (0x65).
