Delta DVP-20PM

3 Devices
Notes:
1. If COM2 on a DVP-20PM series motion controller is used as a slave station, no
communication instruction can exist in the program in the DVP-20PM series
motion controller.
2. If the STOP/RUN switch on a DVP-20PM series motion controller is turned
from the RUN position to the STOP position after the communication format of
COM2 is modified, the new communication format of COM2 will not be
changed.
3. If users disconnect a DVP-20PM series motion controller and then power it up
after they modify the communication format of COM2, the new communication
format of COM2 will be restored to its factory setting.
Example 2: Modifying the communication format of COM1
If users want to modify the communication format of COM1 on a DVP-20PM series
motion controller, they have to add the program shown below to the top of the
program in the DVP-20PM series motion controller. After the STOP/RUN switch on
the DVP-20PM series motion controller is turned from the STOP position to the
RUN position, the state of M1138 will be detected during the first scan cycle. If
M1138 is ON, the setting of COM1 will be changed in accordance with the value in
D1036.
The communication format of COM1 is changed to the ASCII format 9600, 7, E 1
(9,600bps, 7 data bits, even parity bit, 1 stop bit).

Notes:
1. If the STOP/RUN switch on a DVP-20PM series motion controller is turned
from the RUN position to the STOP position after the communication format of
COM1 is modified, the new communication format of COM1 will not be
changed.
2. If users disconnect a DVP-20PM series motion controller and then power it up
after they modify the communication format of COM1, the new communication
format of COM1 will be restored to its factory setting.
Example 3: Modifying the communication format of COM3
The communication format of COM3 is 7, E 1 (7 data bits, even parity bit, 1 stop
bit). If users want to change the communication speed of COM3 on a DVP-20PM
series motion controller to 38,400 bps, they have to add the program shown below
to the top of the program in the DVP-20PM series motion controller. After the
STOP/RUN switch on the DVP-20PM series motion controller is turned from the
STOP position to the RUN position, the state of M1136 will be detected during the
first scan cycle. If M1136 is ON, the setting of COM3 will be changed in accordance
with the value in D1109.
The communication speed of COM3 is changed to 38,400 bps.
