Slot number and ID number assignment
When the sensor amplifiers are connected to the DL-PD1, slot numbers are assigned to
each sensor amplifier. When using the acyclic communication with the DP-V1 service or
diagnostic function used, the slot number is used to specify the target sensor amplifier
for communication.
Also, ID numbers are assigned to the control output and external input of each sensor
amplifier in the connection order of sensor amplifiers. ID numbers are used to identify
the control output of the sensor amplifier assigned as cyclic communication data.
(Configuration example)
Point
Slot numbers and ID numbers are automatically assigned in the
connection order for sensor amplifiers. If the number of connected
sensor amplifiers or connection order is changed, the control program
may have to be changed. Design the sensor amplifier configuration
and control program with this taken into account beforehand.
