Memory Switch
Memory switch is a MCU internal memory for communication settings.
There are two methods for setting, such as MCU setting and F159 (MTRN) instruction
.
What is MCU setting
This is a setting display by the programming tool that is exclusive for FP2 Multi
Communication Unit. The detailed settings for various communciation conditions and unit No.
etc, are available, however, the mode setting is not available.
Setting procedure using FPWIN GR (Ver 2.4 or later version is necessary.)
The MCU setting is not possible online. Go offline, and download after specifying the MCU setting.
Note:
When using FP2 CPU unit, the system register “No. 2 Configuration capacity setting” should be set to 2k
word in advance. When using FP2SH, this setting is not necessary.
1. Start up “MCU setting” on the “Option” menu.
2. “MCU select the Slot No.” dialog box is shown.
3. Specify the communication conditions correctly in the display below.
Setting using F159 (MTRN) instruction
The communciation conditions for each COM. port can be specified or changed by using F159 (MTRN)
instruction during the ladder program.
