Allen-Bradley 1756HP-TIME Time Synchronization Module

1756HP-TIME Time Synchronization Module Overview Functionality Enables precise time synchronization within a redundant control system Supports both RSLogix v16 and RSLogix v19 (includes Precision Time Protocol or PTP) Wallclock Discipline In RSLogix v16, the user can set the wallclock by writing the current UTC value to it Uses the PPS (Pulse Per Second) bit to discipline the clock every second Wallclock accuracy depends on the remote rack’s RPI (Remote Programmed Input) and the module’s RPI PTP (Precision Time Protocol) When using CIPSync (PTP) in RSLogix v19: Enable PTP output in the module’s configuration Configure the Ethernet bridge module (EN2T, EN2TR) to support CIPSync The Logix Controller synchronizes to the Ethernet Bridge, which in turn syncs with the 1756HP-TIME module Provides better time accuracy compared to other methods Installation Connects to IRIG-B network via BNC connector Requires an RJ45 connector for Ethernet communication GPS antenna connects via an SM
