Product Description
The Allen-Bradley 1756-TIME module is a ControlLogix GPS time synchronization module that provides accurate time across various interfaces using protocols like IRIG-B, PTP, and NTP. Powered by the ControlLogix backplane, it features Ethernet ports, a GPS antenna connector, and an IRIG-B connector for master/slave clock configuration. Configured via Studio 5000 Logix Designer with initial IP address assignment via BOOTP/DHCP, the module installs in any 1756 ControlLogix chassis slot. It's essential for accurate time-based reporting, event triggering, timestamping, troubleshooting, and data analysis in multi-device control networks. Integrated Ethernet, IRIG-B, and GPS antenna connections are included, along with status indicators (PPS, SPS, SYNC, OK) for monitoring time source lock and module health.
Is Your Device Showing These Signs?
The Allen Bradley 1756-TIME module commonly experiences issues such as a failed battery causing loss of real-time clock data, resulting in inaccurate timestamps and potential sequencing errors within the PLC program. Corrupted firmware necessitates a re-flash to restore proper module operation and prevent communication faults on the ControlNet network. Backplane connectivity problems, including corroded or damaged pins, disrupt communication between the module and the PLC chassis, leading to diagnostic errors. Capacitor degradation impacts the module's power regulation, causing erratic behavior and inaccurate timekeeping.
