interface
variable name
4.10 DP/CANopen/PN communication channel
The VFD uses function code P27.26 to control the data volume (send by two groups)
exchanged between the PLC card and VFD to reduce communication time. By default,
P27.26 is 0x03, indicating only the data exchanged through the interfaces mentioned earlier
is involved. If you want to enable the DP/CANopen/PN communication channel for the PLC
card, change the value of P27.26 accordingly. P27.26 is described in the following.
