Technical Reference Manual
Each change (rising or falling edge) detected in the status of a digital input is time-
tagged at an accuracy of ±1 ms. The time tag represents the moment (time) of the
latest input change of the value attribute. The time is not recorded until the filtering
time of the status change has elapsed, which means that the filtering time does not
affect the time tag value.
Count (BI#Count)
The count attribute indicates the number of positive input transitions of a filtered
input. The frequency range of a digital input parameterized to operate as a pulse
counter is 0...100 Hz. If a digital input is changed into a pulse counter, the attribute
BI# is frozen at the value valid at the moment of the change.
The example below shows how the attributes of the digital input 1 (PSC_7_BI1 on
PSC1 module) of REC 523 are named for the configuration:
PSC_7_BI1IV; digital input invalidity
PSC_7_BI1; digital input value
PSC_7_BI1Time; time tag
PSC_7_BT1Count; counter value
Digital outputs
General
The outputs of REC 523 are categorized as follows:
• HSPO High-speed power output, double-pole contact.
• SO Signal output, either NO (Normally Open) or NO/NC (Normally Open/
Normally Closed) contact.
