Manage EIP Traffic with No Configuration!

Moxa now has a version of their managed switch that has IGMP snooping enabled out of the box. This means that you can install this switch and manage that pesky EIP traffic without ever logging on to the switch. As inventor Ron Popeil says, "Set it and forget it"!

Some Moxa switch models are available with a -EIP model number. The difference between an EIP and a non-EIP switch is a configuration setting. The EIP models are factory configured for IGMP snooping.

Non-EIP

EIP

Firmware in both switches is the same. Both will forward EIP traffic. Both can be accessed via an Allen Bradley ControlLogix add-on instruction. The part number difference is only to enable IGMP snooping by default. The non-EIP switch can be configured to be a -EIP switch by making the configuration change above. Note: one switch in the network must be enabled as the Querier.

Prepare Windows 7 for Wonderware Products

Installing Wonderware products to a computer has gotten far easier with the new one-disk install. There are a few things, however, the OS needs set as a best practice before installation.

Step 1 
Disable Data Execution Prevention: bcdedit.exe /set {current} nx AlwaysOff

Step 2 
Disable User Account Control: Control Panel, User Accounts, User Account Control, and lower the slider to the bottom. This will require a computer restart.

Step 3 
Firewalls can keep a computer safe from intrusions. They also hinder Wonderware communications if left with default settings. Either shut your firewall completely off or add a series of exceptions:

InTouch

• slssvc.exe
• wm.exe

InSQL or Historian

• InSQLData.exe
• InSQLConfig.exe
• InSQLSCM.exe
• InSQLRet.exe
• SQLServr.exe

General Ports

• 445 tcp
• 1434 udp
• 1433 tcp
• 135 tcp
• 102 DAS SI Direct
• 502 DAS MBTCP
• 2221 DAS ABTCP
• 2222 DAS ABTCP
• 2223 DAS ABTCP
• 5413 S/L DA Servers
• 44818 DASABCIP
