Input parameters
• SSNR: Safety subroutine number
Permitted value range: 1 ... 200
Format: Byte-constants KB001 ... KB200
(further infotmation about the
SSNR can be found in the
sections “Administration data blocks DB015, DB016 and
DB017” and “Input parameter
SSNR” in chapter 5).
Value of DW0000/DB015 = 0: no error present
• S1: N/C contact to be monitored (check with test pulse)
• BASE: Setting the time base
BASE = M110.00 (RLO = 0): time base of 50 ms, multiplied by
T_V gives a possible range of 50 ms to 27.3 min
BASE = M110.01 (RLO = 1): time base of 100 ms, multiplied
by
T_V gives a possible time range of 100 ms to 54,6 min
• T_V: Multiplier for BASE, to determine the length of time the enable
signal should be delayed
Permitted value range: 1 ... 32767
• T: Timer, which measures the set time
• AuSt: Automatic start (reset)
AuSt = M110.01 (RLO =1): automatic start (without reset)
AuSt = M110.00 (RLO =0): no automatic start
• RSET: Reset button (N/O)
