Appendix 3 Details of Remote Buffer Memory
This section describes the details of the remote buffer memory.
(1) Mode switch
Set the mode for all channels.
Setting a value other than the above results in the error code (0730H) being stored in Latest error code (RWr0),
Error flag (RXA) turning on, and the ERR. LED lighting up, with Automatical judgment mode (9H) set up.
(a) Enabling the setting
1. Turn on and off Initial data setting request flag (RY9).
2. Check that "0920H" is stored in Latest warning code (RWr1).
3. Turn off and on the power supply.
(b) Default value
The default value is Automatical judgment mode (9H).
(c) Remote buffer memory address
The remote buffer memory address of this area is as follows:
(2) Conversion speed switch
Set the conversion speed for all channels.
In trigger conversion mode or synchronous communication mode, setting the conversion speed to 1ms/channel
(1H) results in operation at 400μs/channel.
A value out of the range above results in the error code (0360H) being stored in Latest error code (RWr0), Error
flag (RXA) turning on, and the ERR. LED lighting up.
(a) Enabling the setting
Turn on and off Initial data setting request flag (RY9) to enable the setting.
(b) Default value
The default value is 400μs/channel (0H).
(c) Remote buffer memory address
The remote buffer memory address of this area is as follows:
Mode Setting value
Normal mode 0H
Trigger conversion mode 1H
Automatical judgment mode 9H
Remote buffer memory name Main A/D converter module Extension A/D converter module
Mode switch 0000H
Conversion speed Setting value
400μs/channel 0H
1ms/channel 1H
100μs/channel 2H
Remote buffer memory name Main A/D converter module Extension A/D converter module
Conversion speed switch 0001H
