Description Data range
$N140:x UINT[n] n Output assembly of the logic output, confi-
gured via the
input data block 4 to 5
in
samosPLAN 6,
x = 0 to 9, n = 10 – x
0 to 65535
$N141:x UINT[n] n Output assembly of the logic output, confi-
gured via the
input data block 4 to 5
in
samosPLAN 6,
x = 0 to 4, n = 5 – x
0 to 65535
The data range of the number of elements is relative to the assembly sizes. See the table Overview
of assembly databytes of the SP-COP2-ENI module [ch. 8.5.1, p. 97]

Typed Read
The SP-COP2-ENI module supports “Read PLC-5 input” according to the following table:
Table 55: Read request data structure of PLC-5 word range
Name Data type Description Data range
Packet offset UINT Offset in number of elements
Total Transaction UINT Number of elements in the transac-
tion 0 to value dependent on
the assembly 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
The answer of the SP-COP2-ENI module is listed in the following table. The first byte of the type 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 ty-
pe of size 2.

The command data of all assembly instances can be recorded using “Read input”.
In contrast to native addressing of EtherNet/IP assembly instances, the PLC-5 system address con-
tains an element offset which can be used.
The SP-COP2-ENI module supports fields (arrays) of UINT as PCCC data types. Due to the odd size of
the assembly instance 57, the firmware contained in the SP-COP2-ENI module assigns an additional
byte, to provide an even number of bytes.
The address scheme supported by the SP-COP2-ENI module for Read PLC-5 input is shown in the
following table:
