Controlling the Digital Outputs

CM35 Counter Module
(4) J31069-D0416-U001-A5-7618
You can control the digital outputs of the CM35 as shown below, based on
the parameterization of DO mode.
DO mode:
Automatic: Note:
A parameterization bit can be used to specify whether
the DO byte is to control the enable
or whether the enable is continuous.
Enable mode = ² ² ² ² Enable control via DO byte² ² ² ²
The DO byte is used to enable the output for
control via the counter status.
0: Output disabled
- - The output is not switched on with the start of
counting.
- - A switched on output is forcibly switched off.
1: Output enabled
- - The output is switched on at start of counting.
- - The output is switched off when the comparison
value is reached or counting is stopped.
Enable mode = ² ² ² ² continuous enable² ² ² ²
Control via the counter status is continuously enabled for
the outputs. A switched on output can be forcibly switched
off with the DO byte.
0: A switched on output is forcibly switched
off.
(The forced switch- - off only affects the current
counting procedure.)
1: No effect
CPU control: You specify the state of the output with the DO
byte.
0: Switch off output
1: Switch on output
Write the DO byte to the address ²module start address + 0.²
Note
Control of the digital outputs must be programmed with a word access.
