See Chapter 5 for more information. The factory IP setting of the MB-GATEWAY module is to retrieve an IP address via DHCP. In order to see what IP address has been assigned and/or to change that setting the NetEdit software tool will be required to discover and configure the MB-GATEWAY TCP/ IP settings.

The IP address, Subnet Mask and Default Gateway address can be configured on this page. You may lose communications with the MB-GATEWAY module if you configure an IP address and/or Subnet Mask that is not compatible with the subnet of your PC’s Network Interface Card. You may be required to change the subnet settings of your PC or use the NetEdit tool to regain communications in this situation.

Modbus RTU serial nodes connected to the MB-GATEWAY module. In some situations, such as a high amount of electrical noise, poor cabling, etc., it may be necessary to reduce the baud rate on the MB-GATEWAY module AND serial devices on the network.
Page 34: Set Up Slave Timeout / Retries Page
The way that the timeout and retry field is utilized is: The MB-GATEWAY will send a request to the serial device, if there is no reply from the device within the Timeout value specified, the MB-GATEWAY will send another request and wait again.

Page 41: Chapter 5: Automatic Read Feature
Chapter 5: Automatic Read Feature Automatic Read Feature The Automatic Read Feature allows the MB-GATEWAY module to utilize some of the idle time that usually occurs between Modbus TCP requests from the Client device. Note that this feature only allows the reading of data from the serial devices and not writing to them.
Page 42: Situation 1
“Unit ID” number that is sent within the Modbus TCP header that is typically used to target a Modbus RTU node that is on the serial side of the MB-GATEWAY. Therefore, the Node number that is assigned to the MB-GATEWAY module should be unique from any Modbus RTU nodes on the serial network.

Page 45: Situation 2
Other devices Step 1: Before a request even comes in on the Ethernet side, the MB-GATEWAY is reading data from the serial slaves at the “Inter-packet TX Delay” rate and placing that data into its local cache. MB-GATEWAY-USER-M Hardware User Manual, 1st Ed. Rev. G 02/20...
Page 46 Other devices Step 3: MB-GATEWAY immediately generates TCP reply and sends back to Client device from local cache without generating a new serial request. The response time for the TCP request will be significantly faster when the request is targeted at an address in the Automatic Read table.
Page 47: Additional Optimization
Chapter 5: Automatic Read Feature Additional Optimization An additional method of optimization is used in the MB-GATEWAY. If a request is sent to the MB-GATEWAY from the Modbus TCP Client targeted at a Node number and starting address that is equivalent to an entry in the Automatic Read table, the MB-GATEWAY will treat the request as if it had been targeted at the MB-GATEWAY Modbus address and will respond from its local data cache since the data is the same.
Page 48: Automatic Read Status Data
Another way that is very common and is seen often in AutomationDirect products is the use of the Modicon style addressing. This method employs a PLC style address that contains a Modbus memory type in the highest digit of the address followed by the offset from 1.
