Use DXNET+

This option must be enabled if a newest PLC, which uses the DXNET+ protocol, is in use. This protocol adds 1 (one) signature byte to each communication frame, which prevents that, in case of response delays, this Driver considers as a response to a command a delayed response to a previous command, which returned a time-out error. This error may generate, among other problems, false alarms in an application. This signature byte is sent to a PLC in each request of this Driver, and must be echoed in the response of a PLC, with its value incremented at each communication. Using PLCs with a firmware that implements this protocol is highly recommended in case of communication networks that may present lengthy random delays when answering. In networks that do not present this behavior, users can avoid this problem by properly configuring a time-out

Station Code

A String with a 10-character code to be read from the modem of a PLC and checked by this Driver, right after connecting and writing this password by this Driver. If the value read from the modem of a µDX PLC does not match the value configured in this Driver, connection is interrupted

Station Password

An 8-bit number value, between 0 (zero) and 255, that represents the password to write to the modem of a µDX PLC right after connecting to this Driver. If the written value does not match the value configured in the modem of a PLC, it interrupts the connection right after writing

Code read retries

Number of attempts to read the code of a modem, in case of communication error

Modem DXNET address

DXNET address of a modem from a µDX PLC

Modem DXNET group

DXNET group of a modem
