Serial Communications
Overview
The SMC Dialog Plus controller can be started and stopped through
programmable logic controllers using an optional communication
module. Additionally, parameter data can be read to the logic
controller through data transfer. The amount of information that can
be transferred from the SMC Dialog Plus controller is determined by
the DIP switch settings on the communication module.
Note: Parameter values modified while the motor is operating are
not valid until the next start sequence begins.
Logic Control Data
The information in Table 8.A provides the logic control information
that can be sent to the SMC Dialog Plus controller through the logic
controller’s output image table.
Table 8.A Logic Control Data
①
Only one bit may be asserted at any given time.
②
The stop bit will take priority in operation when more than one bit is asserted. Other bits will be ignored until the stop bit is reset.
③
A 0 to 1 transition is required for a valid command.
④
Assert the Option Command bit to initiate an option maneuver such as Pump Stop.
Control Wiring
Refer to Figure 3.14 on page 3-10 for the applicable wiring diagram
to achieve start-stop control via the SCANport.
