24 string monitoring units
Interface parameters
The type S1 string monitoring module PVCBM-GR24 supports the
modbus RTU protocol with the following interface parameters:
Baud rate 1200 to 38400 Bd
Format 8n1, 8e1 or 8o1
Max. cable length 1.2km
Unit load 1/8
Byte order MSBit-LSBit
Word order LSByte-MSByte
Address range 1 – 247
Max. frame length 256 Bytes
The following are supported as function codes:
03 Read contents of a holding register
04 Read contents of an input register
06 Write contents of a R/W register (preset single register)
For reading the registers the following therefore arises:
