Siemens S7-1500 CPU EtherNet/IPTM IO Scanner Software

Generic Ethernet Module

The EtherNet/IP IO Scanner Function Blocks communicate with EtherNet/IP Adapters supporting Implicit Message Class 1. A demonstration mode is not supported. This is a software solution which utilises the existing Ethernet capabilities of the S7-1500 PLC system to allow connection of multiple EtherNet/IP Adapters when a Layer 3 Router is used in conjunction with the Sigma Function Blocks. This feature enables the IO of all connected IO Adapters to be checked every scan cycle of the PLC*.

The Function Blocks allow the S7-1500 PLC to act as an EtherNet/IP IO Scanner.

The supplied Library contains the following

  • Generic Ethernet Module GEM Function Block

  • Generic Ethernet Module UDT

  • I/O Example Data Block

 

  • Generic CIP Message GCM Function Block

  • Generic CIP Message UDT

  • MSG Example Data Block

* The Produce/Consume model is employed by the Sigma Function Block and therefore the IO updates will be based on the RPI of the Adapter and this RPI must be not less than the PLC CPU longest cycle time. A Layer 3 Router provides Source Port Forwarding of the I/O Adapters UDP packet destination port from 2222 to the configured S7-1500 I/O Adapter port number.

The Manual and instruction videos provide the guidance to easily connect a Siemens S7-1500 PLC with EtherNet/IP Adapters.

Terms & Conditions

The Sigma S7 EtherNet/IPTM functions are licenced for use in a single compatible Siemens S7 CPU and the licence is not transferable to another CPU.

THE SOFTWARE IS PROVIDED “AS IS” WITH NO WARRANTIES WHATSOEVER, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE.

Personnel who develop PLC software programs for Siemens Simatic S7 PLC’s communicating with IO Adapters via EtherNet/IPTM must be suitably qualified and must only use the supplied software functions for their intended use and supervise the health of the EtherNet/IPTM communication link to ensure that human and machine safety are adhered to at all times. Qualified personnel must determine for themselves the suitability of this software for the intended use.

We have checked the contents of the software and documentation manual with regard to its accuracy with the described software. Deviations cannot be excluded. Therefore, we cannot guarantee its complete conformity.  The Software Manual contains the description of the software Functions valid at the time of publication. The technical data contained in the software manual is subject to change.
