9.2.3.5 Central control and status words
The central process data exists for different telegrams. For example, telegram 391 is used
for transferring measuring times and digital inputs/outputs.
The following central process data are available:
Receive signals:
● CU_STW1 Control Unit control word
● A_DIGITAL digital outputs
● MT_STW probe control word
Transmit signals:
● CU_ZSW1 Control Unit status word
● E_DIGITAL digital inputs
● MT_ZSW Probe status word
● MTn_ZS_F Probe n measuring time, falling edge (n = 1, 2)
● MTn_ZS_S Probe n measuring time, rising edge (n = 1, 2)
