Communication
(CompoWay/F)
Channel identifier
For multi-point input types that require settings for channels 2 to 4,
specify 1 to 3 to identify the channels.
On single-input types, only "0: Channel 1" can be specified.
In-area address
This is a number that is assigned to each set of data in the variable
area. Addresses are assigned in order beginning from the first set.
For more information on addresses, see "Appendix Setting list" (P.A-
6). Note that the addresses indicated in the setting list are
addresses of channel 1.
For example, to specify an address of channel 2, add 0100 to the
address in the setting list. For channel 3 add 0200, and for channel 4
add 0300.
● Number of
elements
The number of elements is expressed as a 2-byte hexadecimal
number. The specification range for the number of elements varies
depending on the command. See "6.9 Commands and responses
(Communication/CompoWay/F)" (P.6-14) for more information.
For example, if the number of elements is 0010, the first 16 elements
of data (H'10) from the address are specified.
● Set values Values read and written to the variable area are expressed in
hexadecimal and disregard the decimal point position (negative values
are expressed as a two's complement).
Example: D'105.0
→ H'0000041A
The variable is an 8-digit number in hexadecimal. Negative
values are expressed as a two's complement. The decimal is
disregarded.
For example, if the PV of the E5AR/ER is 105.0, it will be
read as H'0000041A (105.0
→ 1050 → H'0000041A).
