After these parameter settings are done, set Confg _Ex to TRUE and then Mng_Open to TRUE. If the
configuration need be modified during the communication, the input Confg_Ex should be triggered on
the rising edge, Mng_Open should be set to FALSE and then to TRUE after the new configuration data
are set up.
The node address of the slave DVP32ES2 is 1. The values in 31 bit devices %MX0.0~%MX3.6 of the
master are written to Y0~Y30 in the slave. Then the values in Y0~Y30 of the slave are read and stored
in the 31 bit devices %QX0.1~%QX3.7 in the master as shown in the following variable table 2.
