Consistency Rules for Inputs Interface
The input interface requires that the sensor power supply remains active for counting operations.
When the sensor power supply interrupts lasts 1 ms or less, the counter remains stable.
In case of power interrupt is greater than 1 ms, all counter values are disabled.
By default, the sensor supply fault makes the CH_ERROR (%Ir.m.c.ERR) global status bit at the high level and the red led IO lighted.
The configuration screen allows to unlink the sensor supply fault to the CH_ERROR bit by configuring the parameter Input Supply Fault as local instead of General IO Fault.
IODDT_VAR1 is of the type T_Unsigned_CPT_BMX or T_Signed_CPT_BMX
Consistency Rules for Outputs Interface
The output interface requires that the actuator power supply remains active for output blocks functions operations.
When the actuator supply voltage is insufficient the ouputs are held to 0 V.
By default, the actuator supply fault makes the CH_ERROR (%Ir.m.c.ERR) global status bit at the high level and the red led IO lighted.
The configuration screen allows to unlink the actuator supply fault to the CH_ERROR bit by configuring the parameter Output Supply Fault as local instead of General IO Fault.
IODDT_VAR1 is of the type T_Unsigned_CPT_BMX or T_Signed_CPT_BMX
