triggered by the instruction TO. After 1 is written in CR#21, the sending/receiving of the packets 
in group 1 will be triggered. After 2 is written in CR#21, the sending/receiving of the packets in 
group 1 will be triggered.

Triggering the sending/receiving of 
the packets in a group through COM1 
 
The sending/receiving of the packets in type 1~type 5 is controlled by M1~M5. The slave ID of 
the power meter is written into D0, and the parameter index is written into D1. If users want to 
write a value in a register, the low byte is in front of the high byte. For example, if the salve ID of 
the power meter is 5, the value written into D0 is 16#0500. The value stored in D100 is read in 
the same way.
