Assignment digital input DI 0, 1, 2, 3
A command trigger can be assigned to a digital input. This is done on the basis of the
command number: → Command lists (Page 147).
Assignment input DI.0, 1, 2, 3:
Command code is triggered at a rising edge (1->0 transition)
The speed sensor is connected (up to approx. 5 kHz)
Message to SIWAREX "Belt switched on"
75 (only DI .1) Belt revolution sensor for calculation of belt for exact triggering of revolution
Input filtering (hardware setting)
To ensure that the inputs do not respond too quickly to the signal change, a minimum signal
pending time can be specified. The pending signal is not processed further until this time has
elapsed.
The following values can be set:
3 0.8 ms 7 12.8 ms
Assignment digital output DQ 0, 1, 2, 3
A status display can be assigned to a digital input. This is done on the basis of the bit
number.
Assignment output DQ.0, 1, 2, 3:
Bit no. of the status flags from bytes 0 to 3 (DR 30)
Bit no. of the status flags from bytes 0 to 3 (DR 30), but inverted
Controlled via data record 18
Controlled via S7 I/O modules
