Symbol “R” refers to read only; “R/W” refers to read and write.
M W # 0 : N u m b e r o f D e vi c e s M o n i t o r e d
Explanations:
For setting up the number of devices to be monitored. Max. data in 16 slaves can be monitored.
b15 is read only (Default =1: normally enabled cache mode)
M W # ( O d d N u m b e r ) : N o . o f Sta t i o n M o n i t o r e d
Explanations:
MW#1, MW#3, MW#5…MW#33 are for setting up the station No. (0 ~ 255) to be monitored.
M W # ( E ve n N u m b e r ) : A d d r e s s o f D e vi c e M o n i t o r e d
Explanations:
MW32, MW34, MW#36…MW#34 are for setting up the address of the device to be monitored.
