- Coordinates PLC-3 I/O scanning while processing stored operator and report messages
- Allows stored messages to be initiated from a terminal or by ladder MSG instructions
- Requires the original scanner number, channel assignments, and serial-device configuration to be preserved
1775-S4B is an Allen-Bradley plc-3 i/o scanner-message handling module designed for the documented PLC-3 control platform.
Channel 5 provides the documented RS-232-C interface for report-generation devices. Messages can be stored from a terminal and executed directly or by a ladder MSG instruction.
Before installation or replacement, identify all channel 5 devices and preserve their serial configuration. Back up stored messages and the ladder logic that triggers them.
Availability, condition, price, and shipping time for 1775-S4B are confirmed during quotation.
