CONTROL Command (Control Remote Bit)
Use the CON command (see Table 7.11) to control remote bits (Relay Word
bits RB01–RB32). You can use the CON function from the front panel
(
Control > Outputs
) to pulse the outputs. Remote bits are device variables
that you set via serial port communication only; you cannot navigate Remote
Bits via the front-panel HMI. You can select the control operation from three
states: set, clear, or pulse, as described in Table 7.12.
For example, use the following command to set Remote bit RB05:
