PLC writes output data sets
The following restrictions apply when the PLC writes the output data sets:
• The equipment index must not be equal to zero.
• The telegram must be sent in Word format.
• All output data sets are transmitted to the PLC in 16-bit word format, with the first byte having
to be placed as the lowest value, i.e. on the far right of the integer, while the second byte will
have the highest value, i.e. on the very left of the integer.
PLC polls the input data sets
• The following restrictions apply:
• The equipment index must not be equal to zero.
• The PLC variable that is to incorporate the data must meet the following conditions:
– It falls into the address range 40xxxx (for Schneider Modicon PLCs).
– There is an array of 16-bit words that is long enough to accommodate the entire output da-
ta set.
• All input data sets are transmitted to the PLC in 16-bit word format, with the first byte having
the lowest value, i.e. on the far right of the integer, while the second byte has the highest value,
i.e. on the very left of the integer.
NOTICE
Configure the PLC data polling in such a way that a data telegram is exchanged at least every mi-
nute between SP-COP2-ENI and the PLC. The TCP connection will otherwise be interpreted as not
used and terminated.
NOTICE
The data from the PLC to the SP-COP2-ENI module assumes the value zero in the samosPLAN 6
logic program if the Modbus TCP connection is terminated by the PLC itself or by a timeout.
SP-COP2-ENI as slave – data addressing
The following table lists the addresses for reading out the data sets.
