The measuring system must have a safety-related configuration before it can establish a connection
to an originator. When the measuring system is delivered, it does not have a safety-related
configuration and must therefore first be configured accordingly.
The measuring system performs a self-test if the supply voltage is turned on in this state. After a
successful self-test it is checked whether the measuring system was assigned a valid TUNID. After a
successful self-test, the measuring system changes to the CONFIGURING status and waits for a
configuration to be assigned. This state is exited only after a valid configuration has been made.
If the measuring system has already been put into operation and has a safety-
related configuration, this safety-
related configuration must be deleted for safety
reasons before the measuring system can be installed in a safety network.
If this is the case, follow this procedure:
1. Reset the measuring system to factory settings
2. Assign a TUNID
3. write the safety-related configuration
The safety-related configuration can be deleted by using the SNCT tool
Device Applet, by using the SNCT download and by using the function Reset.
Alternatively, delete the configuration by using the rotary switch, see Chapter 5 on
Page 39. This sets the factory settings for TUNID, SCID, the
configuration, and the password
. The measuring system is then reset to the
as-delivered status and remains in the WAITING FOR TUNID
voltage was turned OFF/ON, see Chapter 3.5 on Page 29.
The measuring system supports both SafetyOpen connection frames of Type 1 and Type 2.
Originators that support Type 1 SafetyOpen connection frames can configure the measuring system
completely and simultaneously establish connections to the measuring system. The originator
performs the entire configuration process (download, test, and verification).
The description of the configuration process is not part of this manual. Please refer to the
documentation associated with the control system instead. However, do observe the
instructions in Chapter 2.2 on Page 14.
Originators that only support Type 2 SafetyOpen connection frames cannot configure the
measuring system. The safety-related parameters SNN and SCID must be configured with
TR-Electronic’s own SNCT tool TR SNCT Device Applet. Apply the values calculated in this way
to the control system configuration.
Appropriate downloading, testing, and verification functions have been implemented in the
configuration tool. The safety configured measuring system can then be connected to the originator
and establish connections.
The safety-related Type 2 SafetyOpen configuration with download process and verification process
meets the CIP NETWORKS LIBRARY Volume 5, Alternative 3 requirements:
Download and function test with various subsequent comparison processes.
