ASCII MODBUS

A Modbus protocol message framing format in which ASCII characters are used to 

delineate the beginning and end of the frame. ASCII stands for American Standard 

Code for Information Interchange.

boolean

a type of data point that can only take on values of TRUE or FALSE (generally TRUE is 

represented by a value of 1, FALSE is represented by a value of 0)

bps

CPU

central processing unit

CTS

Clear-to-Send; the RS-232C handshaking signal input to a transmitter indicating that 

it is okay to transmit data – i.e., the corresponding receiver is ready to receive data. 

Generally, the Request-to-Send (RTS) output from a receiver is input to the Clear-to-

Send (CTS) input of a transmitter.
