General information about MODBUS RTU
The MODBUS RTU structure uses a master-slave system to
exchange messages. It allows a maximum of 247 slaves,
but only one master. The master controls the operation of
the network and only it sends the request. Slaves do not
undertake transmissions on their own. Each communication
begins with the master making a request to the Slave, which
responds to the master with what it has been asked. The
master (computer) communicates with slaves (controllers)
in two-wire RS-485 mode. This uses data lines A+ and B- for
data exchange, which MUST be one twisted pair .

Daisy Chain
No more than two wires can be connected to each terminal,
ensuring that a “Daisy Chain” (in series) or “straight line”
(direct) configuration is used. Star or network (open)
connection is not recommended, as reflections within the
cable can cause data corruption.

MODBUS RTU network operation - Slave mode
Engo’s MODBUS controller has the following features when operating as a slave in a MODBUS RTU network:
- Network connection via RS485 serial interface.
- Address, communication speed and byte format determined by hardware configuration.
- Allows access to all tags and data used in the controller’s ladder program.
- 8-bit slave address
- 32-bit data size (1 address = 32-bit data return)
- Each MODBUS data register has a size of 2 bytes.
ATTENTION:
Before the controller is connected to the RS-485 network, it must first be properly configured.
The communication settings are configured in the service parameters of the regulator (device).
ATTENTION:
Connecting unconfigured controllers to the RS-485 network will result in improper operation.
