Max. I/O modules
:
32 modules
●
System setting module
:
3 byte out , 4 byte input
●
Output module
:
Output Relay/Coil => 1~32 Bytes
Output Register => 1~64 Words
●
Input module
:
Input Relay/Coil => 1~32 Bytes
Input Register => 1~64 Words
●
Max. length of I/O data
:
263 Bytes
●
Output length
:
0~131 Bytes
●
Input length
:
0~132 Bytes
The modules have module parameters about the communication settings. The
module parameters are shown in the below
