■Switching mode No. designation (Un\G144/304)
Write the mode No. after mode switching (0001H to 0007H, 0009H, 00FFH).
When "0000H" is designated, the operation will be matched with the setting in MELSOFT.
*1 Specify "00H" for the communication protocol setting when specifying the MELSOFT connection mode with the parameter settings of
Engineering tool.
■Transmission specifications after switching designation (Un\G145/305)
1. Specify the transmission specifications after mode switching.
2. Write "0000H" when returning to the settings configured with Engineering tool.
3. When setting arbitrary transmission specifications (other than the transmission specification set with Engineering tool),
write the value corresponding to ON/OFF of the relevant bit.
*2
The relevant bit 1 (ON)/0 (OFF) is specified as the same
as the transmission setting of Engineering tool.
•For C24
*1 On the side of interface to which "MELSOFT connection" is set for the switching mode No. designation, set all items to the OFF side.
C24 operates with the setting values set with Engineering tool.
