Status of DI for MIX38 and MIX38-IP

Counter 1-12 (40023, 40024-40045, 40046)

The modules have 32-bit counters, one for each digital input.

The register with a lower number contains a lower byte of the counter and in the register with a higher number is stored in the higher byte of the counter. 

In order to change the value of the register, write any value (called ‘preset’) for pulse counting registers. In special cases, the counter can be reset by entering 0. Resetting the counter is also possible with the 40022 register.

Resetting the Counters (40022)

Setting a true value of a particular bit of this 16-bit register results in resetting the corresponding counter (setting it to 0) in accordance with the following table:
