Appendix 2 Details Of Buffer Memory Addresses - Mitsubishi Electric MELSEC L Series User Manual

Appendix 2
The following describes the details of buffer memory.
(1) D/A conversion enable/disable setting (Un\G0)
Set whether to enable or disable D/A conversion for each channel.
(a) Enabling the setting
Turn OFF  ON  OFF Operating condition setting request (Y9) to enable the setting.
(b) Default value
All channels are set to D/A conversion disable (1).
(2) CH Digital value (Un\G1 to Un\G8)
This is the area where the digital value in signed 16-bit binary for performing the D/A conversion is written from
the CPU module.
• The setting range is as follows;
Module Output range setting
0: 4 to 20mA
1: 0 to 20mA
2: 1 to 5V
L60DA4
3: 0 to 5V
4: -10 to 10V
F: User range setting
0: 4 to 20mA
1: 0 to 20mA
2: 1 to 5V
L60DAVL8,
3: 0 to 5V
L60DAIL8
4: -10 to 10V
F: User range setting
*1 When the scaling function is enabled, the settable range and practical range depend on the settings for scaling upper
and lower limit values.
• When the value out of the setting range is written, the D/A conversion is performed with the upper and lower
limit value of the settable range. In addition, a check code is stored in CH Set value check code (Un\G11 to
Un\G18) and the error code (60) is stored in Latest error code (Un\G19), Error flag (XF) turns on, and the
ERR. LED turns on.
