MTL838C Modbus Implementation
This manual is principally intended for instrumentation engineers and technicianswho need to configure the communications between Modbus system hosts and MTL838C or MTL838C-MBT multiplexer receivers. Since both receivers use the Modbus protocol, MTL838C will be used to refer to both models unless otherwise stated.
The manual provides comprehensive information on the Modbus® protocol, describes the communication between the MTL838C and the host, and provides detailed information relating to the functions of the MTL838C. No previous knowledge of Modbus is assumed.
The JBUS® protocol is also supported by the MTL838C. JBUS is virtually identical to Modbus apart from a slight difference in the addressing of slaves, and this manual may be used for both protocols. The difference in slave addressing is explained in the relevant section.
