Word Range Read
The SP-COP2-ENI module supports “Read PLC-5 word range” according to the following table:
Table 51: Read request data structure of PLC-5 word range
Name Data type Description Data range
Packet offset UINT Offset as number of elements
Total Transaction UINT Number of elements in the transaction 0 to value depen-
dent on the as-
sembly size
Address BYTE[m] PLC-5 system address, m >= 2 “0” to “:”, “A” to
“Z”, “a” to “z”
Size UINT Number of elements to be returned
Table 52: Feedback to the SP-COP2-ENI module of Read PLC-5 word range
Name Data type Description Data range
Payload UINT[n] 2•n = number of data bytes (up to 244
bytes) 0 to 65535

Typed Write
The SP-COP2-ENI module supports “Write PLC-5 input” according to the following table:
Table 53: Write data structure of PLC-5 input
Name Data type Description Data range
Packet offset UINT Offset as number of elements
Total Transaction UINT Number of elements in the transaction
Address BYTE[m] PLC-5 system address, m >= 2 See next table
Type ID BYTE[n] Data type and size, n >= 1
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. 89] . The UINT data format corresponds to writing the format of the word range.
