G1506S
EVALUATION UNIT

Addressing

The address has been set to 0 at the factory. Assign a free address between 1
and 31.
Addressing with the addressing unit AC1144
If the mounted and wired module is used with the FC coupling module AC5010
(with addressing socket), it can be addressed via the addressing cable (E70213).
Addressing via the addressing socket is only allowed when the evaluation
unit is disconnected.
If it is used with the FC coupling module AC5000 (without addressing socket) the
evaluation unit must first be addressed via the addressing unit AC1144 and then
mounted onto the lower part.
Infrared addressing
The evaluation unit also offers the option of infrared addressing with the address-
ing unit AC1144.
The AS-i communication (yellow cable) must be switched off during the
infrared addressing. To do so, disconnect the master.
When the ifm AS-i power supplies type SL are used, the communication can be
deactivated via a plug on the power supply.
Supply the slaves with voltage via the AS-i power supply. Infrared addressing is
carried out via the IR addressing cable E70211.

8. Response times

The response time of the evaluation unit to a safety request is max. 220 ms.
Within this period the safety code 0000b (=safe state) is statically transferred.

Calculation of the total response time

For the calculation of the response time of the total system the response times of
the other components also have to be added (fail-safe switch, evaluation unit,
safety monitor and possibly external relays).
Example:
For the fail-safe switch GM503S the response time to a safety request is < 20 ms
and for the safety monitor AC001S < 40 ms. The sum of the individual response
times results in the total response time to a safety request of < 280 ms.
The switching times of external relays also have to be added.
