5.1.2.9 TESTABLE-SENSOR function block (electro-sensitive protective equip-
ment)
The “TESTABLE-SENSOR” function block evaluates the status of electro-sensitive protec-
tive equipment. When the protective field of the electro-sensitive protective equipment is
clear, the output is set to logic “1”. If the protective field is interrupted, the output is set to
logic “0”.

ment)
Manual Reset If this option is selected, a reset must be performed manually every time the function block
is activated. Otherwise, the activation of the output directly follows the state of the inputs.
Reset Type There are two types of reset: “Manual” or “Monitored”. If the “Manual” option is selected, only
the signal transition from “0” to “1” is checked. In the case of the “Monitored” option, the dou-
ble transition from “0” to “1” and back to “0” is checked.

NOTE:
Due to the type 2 safety equipment that is to be connected, up to SIL 1 (EN 62061) and
PL c (EN ISO 13849) can be achieved.
NOTE:
Inputs at a function block must always be used in ascending order.
Example: if Input 1 is used for the function block, Input 2 must be used for the reset input.
