Frequently Asked Questions

How many digital inputs does the DI 16x24VDC ST module provide?
The module provides 16 digital inputs operating at 24 V DC. Inputs are sink type (PNP, P-reading) and conform to IEC 61131, type 3.
What input delay values can be configured per channel?
Input delay is configurable per channel with the following values: 0.05, 0.1, 0.4, 0.8, 1.6, 3.2, 12.8, and 20 ms. An additional delay of 30 to 500 µs depending on line length also applies.
What diagnostic interrupts does the module support?
The module generates diagnostic interrupts for three events: wire break, parameter assignment error, and missing supply voltage. The DIAG LED flashes when a diagnostics event occurs.
What resistor is required when wire-break detection is enabled?
When wire-break detection is configured, a resistor of 25 kΩ to 45 kΩ must be connected in parallel to each mechanical transducer contact so that the required quiescent current can flow when contacts are open.
Which BaseUnit type is required for this module?
The DI 16x24VDC ST requires BU type A0. For 2-wire, 3-wire, and 4-wire connections, a Potential isolation module must be added alongside the BU type A0.
How can module parameters be changed while the system is in RUN mode?
Parameters can be reassigned in RUN using the WRREC instruction to transfer data record 128 to the module. Parameters set in STEP 7 are not permanently overwritten and become valid again after a CPU restart.
What are the operating temperature limits for horizontal and vertical mounting?
For horizontal installation, the operating temperature range is -30 °C to 60 °C. For vertical installation, the range is -30 °C to 50 °C.
