Input and output signals for Pulse output mode
Input and output signals Meaning
Input signal
HW enable You can select the HW enable with the "Func-
tion DI" parameter and select the input delay
with the "Input delay" parameter.
The signal at DIn.0 is interpreted by the
TM Pulse 2x24V, after noise filtering by the
input delay, as the start of the output se-
quence.
Output signal
Pulse at the DQn.A A pulse is output at the DQn.A digital output
digital output for the set pulse duration.

With HW enable: 0 to 15
Reserved Read as 0
Indicates the signal level at the DQn.A digital output.
0 on DQn.A digital output
1 on DQn.A digital output
Indicates the signal level at the DQn.B digital output.
0 on DQn.B digital output
1 on DQn.B digital output
Indicates the signal level at the DIn.0 digital input.
0 on DIn.0 digital input
1 on DIn.0 digital input
Value range
0 = HW enable cleared
1 = HW enable issued
0 → 1 = Start of the output
sequence after the input
delay, dependent on the
software enable
(SW_ENABLE)
0 = no pulse
1 = pulse
