Siemens 3RS2

Example: K2 alarm value at 20 °C (+ delay time):
• In the closed-circuit principle, a cable break is detected if it occurs, and the output relay is
deactivated; the display turns red
– K1 (11/12) is closed
– K2 (21/22) is closed and relay output 33/34 is open on the 3RS29
• In the open-circuit principle, a cable break is detected if it occurs, and the output relay is
deactivated; the display turns red
– K1 (11/14) is closed
– K2 (21/24) is closed and relay output 33/34 is open on the 3RS29

6.5.1 Con󹪝guring with STEP 7 - prerequisites
Procedure when con󹪝guring IO-Link master and IO-Link devices
Con󹪝guration takes place in two steps with STEP 7, V5.4 SP5 or higher:
1. In HW Con󹪝g, con󹪝gure the IO-Link master (with GSD if necessary), e.g. the 4SI SIRIUS
electronics module or 4SI IO-Link (both require at least 󹪝rmware version 1.0.1).
2. With the Port Con󹪝guration Tool S7-PCT (V2.0 or higher) you con󹪝gure the connected
monitoring relay for IO-Link (IO-Link Device).
Requirements
• STEP 7 V5.4 SP5 or higher
• The Port Con󹪝gurator Tool S7-PCT (V2.0 or higher) is installed on the PG/PC. You can either
install S7-PCT together with STEP 7 V5.4 SP5 or higher, or you can download it from Internet
(https://support.automation.siemens.com/WW/view/en/33102519/133100).
• The associated IO-Link IODD 󹪝le (IO Device Description) is installed in S7-PCT. You can
download the IODD 󹪝les for the SIRIUS Devices from Internet (https://
support.automation.siemens.com/WW/view/en/29801139/133100).
• Optional: The GSD 󹪝les are installed in HW Con󹪝g. You can download the GSD 󹪝les for the
ET 200SP from Internet (http://www.siemens.com/comdec).
• Optional: Install the function block FB "IOL_CALL" for backing up/restoring IO-Link master
parameters and IO-Link device parameters. You can download the function block from the
Internet. You can 󹪝nd more information on the function block in Chapter Module
replacement (Page 58).
