● Enabling/disabling the DIP switches and sensor heads
Each channel can be enabled or disabled by switching the DIP switch
ON/OFF.
Example of recommended DIP switch settings (when using 7 sensor
heads)
● ID assignment when connected to a DL Series Communication Unit
Criterion values (measurement values) cannot be output to external
equipment and settings cannot be changed using only this equipment.
Use a DL Series Communication Unit to perform these procedures.
Connect this equipment to the DL Series Communication Unit.
"Connecting to DL Series Communication Units" (page 2)
For details on communication between this equipment and the DL
Series, see the DL Series Communication Unit manuals.
An ID number is automatically assigned to each channel when using a
DL Series Communication Unit.
ID numbers are assigned to enabled channels in order, from channel A
on the main unit.
The example below shows 1 main unit (GT2-500) connected to 2
expansion units (GT2-550) (the expansion unit connected to the main
unit is expansion unit 1, and the expansion unit connected to expansion
unit 1 is expansion unit 2), with 11 sensor heads being used in total.
Example 1: When connected in order from channel A on the main unit
When using DL-RS1A/DL-RB1A
When not using DL-RS1A/DL-RB1A
Example 2: When connected in a random order
When using DL-RS1A/DL-RB1A
Cautions
• If, for example, channel C on the main unit is enabled during use, the
ID for channel C becomes 02, and each subsequent ID has 1 added
to it.
Therefore it may be necessary to change the PLC program.
• When a channel is enabled but no sensor head is connected, it is
recognized as a head error.
When not using DL-RS1A/DL-RB1A
Cautions
• If, for example, channel C on the main unit is enabled during use, the
ID for channel C becomes 03, and each subsequent ID has 1 added
to it.
Therefore it may be necessary to change the PLC program.
• When a channel is enabled but no sensor head is connected, it is
recognized as a head error.
Reference Channel A on the main unit is always enabled,
regardless of the DIP switch setting.
Channel B/C/D/E on the main unit can be enabled or
disabled using the DIP switches.
Channel A/B/C/D/E on the expansion unit can be
enabled or disabled using the DIP switches.
