Title: Problem connecting to PLC5/30 DHRIO
Post by: seth350 on October 13, 2017, 10:04:23 AM

Ive got a ENBT-DHRIO in a contrologix rack that is giving us access to a DH+ network over ethernet.
Theres a SLC and two PLC5/30s on the DH+.

Using the PLC5toDHRIO driver, I am only able to connect to one of the PLC5s and not the other. One is at Node 4 and the other at Node 50.
I am able to go online with both PLC5s over ethernet as well. RsLinx is seeing both of them and can also monitor tags from Linx.

I have looked at the channel config of both PLC5s and the only difference is the baud rate on channel 0.

Driver settings:

CIP Connection Size: 258
DHRIO Slot: 0
PollRate: 500
Port: 44818
RoutePath:
Timeout: 5000

DHRIO Channel: A
Disable Subscriptions: False
IniFileName:
IniFileSection:
Max PCCC Packet Size: 236
Target DHPlus Node: 50

It does generate an exception on startup "Read Failed - 2. Unknown Message - 2"

Wireshark shows the handshake between my pc and the ENBT adapter. Then they begin transmitting "Implicit Data - Class (0xa6)" No visible errors. The wireshark for the working PLC5 doesnt appear any different.

Any ideas?

Try target node 40 (which is decimal for octal 50)
