Product Description
The 1756-HIST1G ME module, designed for ControlLogix chassis integration, features 512 KB of battery-backed SRAM, a 128K L1/128K L2 cache, CompactFlash Type II with DMA, a 10/100T Ethernet port, and a non-removable rechargeable lithium battery. This fanless module consumes a maximum of 7W (5W typical), requiring 5.1V DC at 800mA and 24V DC at 3mA, and operates within a 32-140F range (non-operating: -40-185F). Its single-slot form factor measures 145mm x 35mm x 140mm, enabling backplane communication and data collection from multiple controllers.
Is Your Device Showing These Signs?
The Allen Bradley 1756-HIST1G module commonly experiences issues related to corrupted historical data files, leading to data loss and inaccurate trend analysis. Resolve this by verifying proper configuration of the module's memory allocation and ensuring sufficient storage capacity. Firmware corruption during upgrades causes operational failures; a successful firmware re-flash is required. Communication errors on the ControlNet network disrupt data transfer; troubleshoot by inspecting network cabling, addressing conflicts, and confirming proper network configuration within RSLogix 5000. Power supply fluctuations induce erratic behavior; stabilize the power source and confirm the module operates within specified voltage tolerances.
