We have an HC900 Honeywell controller. It has two 10/100Mbps network modules. E0 is tied to a Windows XP computer running SpecView using a directly connected straight through cable. The other port, E1, is connected to a Cisco 3524XL switch.
This E1 port is hard configured for 100Mbps-FDX, though we have tried 10Mbps-HDX.
We are seeing issues where the controller will hang, the network ports become unresponsive and sometimes the controller sends corrupted Alarm E-mails to our E-mail server on the TCP/IP network.
Am I seeing a negotiations problem with Modbus TCP trying to run on our TCP/IP network?
We are running the very latest honeywell HC900 firmware, which is 4.4.
