WB-MR: Errata

Digital input registers contain 0 instead of the actual signal after switching on

Affected devices

WB-MR and WB-MWAC with firmware v. 1.9.x 1.10.x

Description

After power supply and switching the relay module on, its inputs are not read, in the registers of discrete inputs, the values are 0 even if the input is supplied with 1. The value becomes relevant the first time you switch the input.

=Scheduled fix

Fixed in 1.11.1 When the device is turned on, the state of its inputs falls into the discrete input registers In this case, the output does not react and either disabled or loads the state before switching off from memory if this function is enabled in register 6. The mapping matrix does not process the input. Only if the input mode - 5 is set (leakage sensors with repetition after 20 minutes), the input is processed as an event and the response to it through the mapping matrix. All reactions are performed after further input changes.
