The configuration message thus has the following format:
CFG
byte
Meaning
Permitted values for CFG (hex.)
1
Header
0xC2 (inputs and outputs, 2 bytes manufacturer-specific
data)
2
Length of outputs
0x40
−
0x48 (1 to 9 words of outputs) or
0xC0
−
0xC8 (1 to 9 words of outputs with consistency)
3
Length of inputs
0xC0
−
0xCC or
0x40
−
0x7C (1 to 13 words of inputs with/without
consistency)

Configuration message
When using the 32 bit formats data consistency must always be set.
6.3 Cyclical data exchange
Depending on the configuration, the following data content is exchanged:
6.3.1 Inputs (from MP55IBS to the PLC)
Measured values
Measured values can be communicated in various forms of representation.
The forms of representation available for selection are floating (2 words, 32
bit), 16 bit fixed point number (1 word, 16 bit integer in two’s complement,
decimal place must be known to the reader) or 32 bit fixed point number (2
words, 32 bit integer in two’s complement, decimal place must be known to
the reader). For conversion of the values to fixed point representation the
number of decimal places in the module parameter assignment (display,
CAN-bus) is used as a basis.
