PLC writes output data sets
The following restrictions apply when the PLC writes the output data sets:
• The equipment index must be 1.
• 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 se-
cond 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 be 1.
• 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 out-
put data set.
• All input data sets are transmitted to the PLC in 16-bit word format, with the first byte ha-
ving 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
minute 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 samos-
PLAN5+ logic program if the Modbus TCP connection is terminated by the PLC itself or by a
timeout.

Description/procedure
Determines the transmission method.
Enter the following settings for this purpose:
• Input data: PLC requests
• Output data: PLC writes
Determines which data are to be written to the PLC or
read from it.
Mark the control boxes for the desired data sets for this
purpose.
