Accepting effective ranges and transponders
Introduction
The operational safety of the plant for the most part depends on a good safety plan and a
careful realization of the safety functions.
For safe operation, the project of the HMI device must precisely match the plant.
For this reason when first starting a project in the plant, you must verify all effective ranges
with all transponders. The result of the verification is a CRC checksum that you must enter in
the project. Then you must transfer the project to the HMI device again.
Note
Transponders that are exclusively assigned to one zone are not considered in this
verification.
Acceptance if there are changes
If you change the configuration of transponders and effective ranges in the system, you need
to adapt the configuration. Then you must accept the effective ranges and transponders
again.
Requirement
● In the project:
– Effective ranges and transponders must be configured in the project.
– The project has been transferred to the HMI device.
● In the plant:
– The transponders must be mounted in the plant in such a manner that the effective
ranges stored in the project are formed.
– Batteries must be inserted in the transponders. The ID must be set on the
transponders that is stored in the project for these transponders.
– The IDs of the effective ranges must be marked in the plant.
– The quality of the WLAN range must be sufficient.
– An indicator is installed.
WARNING
An indicator in the effective range is an absolute necessity
A indicator supplies the operator the feedback that he has logged onto the correct
effective range.
Install an indicator in every situation, for example a light that shows that an HMI
device is logged on in the effective range.
