PME-MP55DP
HBM A0582-3.1 de/en/fr
The configuration telegram 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)
4 user-specific data input data selection of the data content
()
5
p
output data
(see Tab 6.3)
Tab 6.4: Contents of the configuration telegram
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.
