PCD7.D7xx terminals as DP Slave

Some of the PCD7.D7xx terminals are available with a Profibus DP option, but this solution is obsolete and we recommend other solutions

The Profibus DP option has the disadvantage that the terminal is a slave and the PCD must organize the data transfer. This means

that an FB per terminal is running in the PCD, which that is creating a significant CPU charge
that the reaction time after user interactions on the terminal gets slow

We therefore recommend other solutions:

Profi-S-Bus is to solution to be used together with new Classic products like the PCD2.M480 and PCD3.Mxxxx, it allows to have several terminals and PCD's on the same bus and the terminals are active participants
MPI is the alternative for xx7 PCD's
Ether-S-Bus or Serial-S-Bus connections are very often an alternative as well
an ESANET network is sometimes interesting, but requires an independent network among the terminals. One terminal acts as Server for the others (Clients). The Server terminal must have two serial ports, one of which connected to the PCD via S-Bus, the other connected to ESANET
