Unit Communications Type (Offset: +7, +10, +13, ... , +97, and +100)
Use the following equation to calculate the offset for a given unit number:
Offset = 7 + (3
× unit number)
Note The command group and segment information settings are valid only when
the communications protocol is set to SYSWAY. These settings are not valid
when the communications protocol is set to CompoWay/F.

Communications
protocol
00, 01,
or 02
Specifies the communications protocol (SYSWAY or CompoWay/F) of the con-
nected component if a component is connected.
00: No Unit connected
01: SYSWAY
02: CompoWay/F
A syntax error will occur and this word’s settings will be invalid if a value other
than 00, 01, or 02 is specified.

Command group
(valid with host
link only)
1 to 5
(BCD)
This setting is valid only when SYSWAY (01) is specified for the communica-
tions protocol. When SYSWAY is specified, the command group determines
which values are read/written when reading or writing data.
The command group setting will be invalid in the following cases:
1) The communications protocol is set to 02 (CompoWay/F).
2) The communications protocol is set to 00 (No Unit connected).
3) The communications protocol is set to 01 (SYSWAY), but the command
group setting is not within the allowed range (1 to 5).

Segment infor-
mation
(valid with
SYSWAY only)
0, 1, or 2 This setting is valid only when host link (01) is specified for the communica-
tions protocol. The segment information specifies whether a Temperature Con-
troller or Digital Panel Meter is connected with the host link protocol.
The segment information setting will be invalid in the following cases:
1) The communications protocol is set to 02 (CompoWay/F).
2) The communications protocol is set to 00 (No Unit connected).
3) The communications protocol is set to 01 (SYSWAY), but the segment
information setting is not 1 or 2.
