Siemens 6ES7547-1JF00-0AB0 SIMATIC S7-1500 CM 8xIO-Link 8-Port IO-Link Master Communication Module

The Siemens 6ES7547-1JF00-0AB0 is a SIMATIC S7-1500 CM 8xIO-Link communication module, an 8-port IO-Link V1.1 master supporting IO-Link protocols 1.0 and 1.1 with up to 8 ports simultaneously controllable. It runs on 24 V DC, 20.4 to 28.8 V, delivers 1 A per port with 4 A total current per module, and mounts directly on the S7-1500 rail.

Technical Specifications

Selection Notes

All 8 IO-Link ports are simultaneously controllable at a 2 ms minimum cycle time, so a fully populated module updates every port without a scan-time penalty for using more channels. Each port carries 1 A, 4 A total per module, enough for most IO-Link sensors and small pneumatic valve terminals but a figure worth checking against actuator inrush current on multi-actuator ports. Master backup stores IO-Link device configurations on the module itself, so a failed sensor can be swapped without re-downloading parameters from the CPU. Ports left unused for IO-Link communication can be parameterized as plain 24 V digital inputs instead.

Applications

Connecting IO-Link V1.1 sensors and actuators, photoelectric sensors, pressure switches, and small valve terminals directly to the S7-1500 backplane without a separate fieldbus gateway, with per-port diagnostics for wire break, short-circuit, and supply voltage monitoring.
