Typed Write

The SP-COP2-ENI module supports "Write PLC-5 input" according to the following table:
Table 49: Write data structure of PLC-5 input
Name
Packet offset
Total Transaction UINT
Address
Type ID
The answer of the SP-COP2-ENI module does not contain any data, only a state, see table
PCCC reply header [ch. 8.4.7.1, p. 92]
of the word range.
Table 50: Write address structure of PLC-5 input
Address Data type Number of
$N37:x
$N138:x UINT[n]
$N139:x UINT[n]
$N140:x UINT[n]
$N141:x UINT[n]
The data range of the number of elements is relative to the assembly sizes. See the table

Typed Read

The SP-COP2-ENI module supports "Read PLC-5 input" according to the following table:
Table 51: Read request data structure of PLC-5 word range
Name
Packet offset
Total Transac-
tion
Address
Size
The answer of the SP-COP2-ENI module is listed in the following table. The first byte of the ty-
pe ID is 0x9a = 0b1001 1010, meaning that the data type is given in the following byte and the
data size in the byte after that. The fourth byte of the type ID is 0x42 = 0b0100 0010, standing
for an integer data type of size 2.
