CH1 Digital value
Set the digital input value in 16-bit signed binary for the D/A conversion from the CPU module.
Output range setting
0: 4 to 20mA
1: 0 to 20mA
2: 1 to 5V
3: 0 to 5V
4: -10 to 10V
E: User range setting (voltage)
F: User range setting (current)
*1 The available setting range and practical range of when the scaling function is enabled differ depending on the setting of the scaling
upper limit value and scaling lower limit value.
When a value out of the available setting range is written, the D/A conversion is performed with the upper or lower limit value
of the available setting range.
A check code is stored in 'CH1 Setting value check code' (Un\G400) and a digital value setting range error (error code:
191H) is stored in 'Latest error code' (Un\G0).
When the wave output function is selected, this area is disabled because registered wave data is output.
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Digital value
CH Digital value (When the Q compatible
mode function is used)
CH1 Wave output start/stop request
This area is for requesting start or stop of wave output to the D/A converter module when the wave output function is used.
The setting for this area is enabled only in the wave output mode. In other modes, changing the setting value is ignored.
Request
Wave output stop request
Wave output start request
Wave output pause request
While 'Step action wave output request' (Un\G188) is set to ON (1), changing the setting value is ignored.
When 'Step action wave output request' (Un\G188) is changed from ON (1) to OFF (0), the wave output status changes to
During wave output stop and Wave output stop request (0) is set for this area.
In the channel where a value out of the setting range is set, a wave output start/stop setting range error (error code: 1D1H)
occurs and 'Error flag' (XF) turns on. The operation of the wave output before the change continues.
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Wave output start/stop request
CH Wave output start/stop request (When the
Q compatible mode function is used)
■Default value
The default value is Wave output stop request (0) for all channels.
