Configuring the MES1A/B Slave Address / Unit ID Source All devices connected to a TCP/IP network require a unique IP address. Each MES1A/B Converter has a unique IP address on the network, allowing messages to be directed to it. However, when multiple Modbus/RTU devices are connected to the RS-485 bus of an MES1B there must be a way to address them individually. Standard Modbus/RTU fields are encapsulated inside Modbus/TCP messages. Modbus/RTU’s Slave Address field is called the Unit ID in Modbus/TCP.
Configuring the MES1A/B • If any Modbus TCP masters on your system use 0 for all Unit ID fields, select a slave address that matches the Modbus/RTU slave attached to your MES1A/B. You will not be able to connect multiple slaves to the RS-485 multidrop bus. Allow Modbus Broadcasts If you configured the Slave Address for any number between 1 and 255 the Allow Modbus Broadcasts does not appear in the menu. When a Modbus/RTU slave receives a slave address of 0 it interprets this as a broadcast message.
Configuring the MES1A/B 0B (hex) - Target Device Failed to Respond • If the slave did not answer, or the answer contained a CRC error • If a TCP socket is open, but no response is received within the defined message timeout period • If a TCP socket is open, but the remote Modbus TCP slave/server returned exception 0B (hex) Disable Modbus/TCP Pipeline Typically a Modbus master issues a query and waits for a response before issuing another.
Configuring the MES1A/B Serial TX Delay after RX When the MES1A/B receives a request from a master it relays the request to the Modbus slave connected to the MES1A/B’s serial connection. When the slave responds a timer is triggered and, after the delay time configured in the Serial TX Delay after TX field, the next master request is allowed to pass through the serial connection to the slave.
Configuring the MES1A/B • If you configure this field for 0 it hold a single socket open to the last remote Modbus TCP slave accessed • If you configure this field for any value between 3 and 60 seconds, it will close the last socket after the configured length of idle time. Redundant Entry Retries After The Redundant Entry Retries After field allows you to disable redundant retries or set a maximum length of time for retries. • If you configure this field for 0 is disables the feature.
Configuring the MES1A/B Slave IP Address Type in the four octets of the IP address of the slaves being addressed. • If you configure the last octet as 000 the MES1A/B will use the Slave Address/Unit ID of the slave as part of the IP address. This allows a Modbus/RTU master (connected through the MES1A/B) to access up to 255 remote Modbus TCP slaves. • If you configure the last octet for a number between 1 and 254, all slave polls in this group will be sent to the same IP address.

Modbus Basics Chapter 6: Modbus Basics If you are reading this manual you are probably in the process of interfacing legacy Modbus ASCII/RTU devices to a network. Chances are you already have some knowledge and familiarity with Modbus ASCII/RTU but possibly somewhat less knowledge of Modbus/TCP and/or networking in general. Most likely your biggest questions relate to what is involved in bringing the two together.
Modbus Basics it sends a message containing a device address, followed by a function code, any data that maybe required, and an error check field. The addressed slave responds with a similar message structure. Typically it repeats back its address and the function code, and then sends a field indicating the number of bytes of data it is sending, followed by the data and the error check field. Slave addresses can range from 1 to 247.
Modbus Basics Another aspect of Modbus/TCP that must be considered relates to the Unit ID field. Modbus/RTU incorporates the slave address field but Modbus/TCP replaces the slave address field with a Unit ID field. TCP/IP uses IP addresses to find specific nodes on the network. By using the IP address to specify the node, and the Unit ID to specify a Modbus/RTU device attached to that node, multiple slaves can be located at a single IP address.
