Connecting to Siemens PLCs
3 - 3 Ethernet Communications
This section provides a description and example of connection to a Siemens
Standard PLC. Connection can be performed to an Siemens Standard PLC
using the FINS/UDP protocol.
Note: Only CP1W-CIF41 Ethernet Option Boards with unit version 2.0 or later can be used.
If another Option Board is used, the G9SP-series Controller will detect an Un-
supported Option Board Error (the MS indicator will flash red).
3 - 3 - 1 Communications Format
Refer to Section 7 Communications with a Standard PLC Using an Option Board of the
G9SP Series Safety Controller Operation Manual (Cat. No. Z922).
3 - 3 - 2 Application Example
System Configuration
This section uses the following example to describe how to access the G9SP-series
Controller from a Standard PLC by performing Ethernet communications through an
Ethernet Communications Board (CP1W-CIF41).
