Compoway-F Communication
Section 3-3
In the next table an overview is presented on how the Free Communication
blocks are composed for several different device types.
A Free Communication block always contains a device address (one word
with a value in the range between 0000 (hex) and 0063(hex)) and a mini FINS
command. The length of the mini FINS command depends on the command
type (operation, write or read) to be executed.
Operation Mini FINS
Command
The Operation mini FINS command type consists of a command code MRC/
SRC, followed by an instruction code, the value of this instruction code is com-
mand type dependent. The operation of a mini FINS command is defined as
follows.
The response of this command for a correct executing of the command is
defined as:
Refer to the operation manual of the targeted Compoway-F device for more
commands and detailed information.
Example
To stop control on channel 1 of the E5_R, with address 05, the contents of the
Fee Communication block must be set to 0005 3005 0101 (hex), or
• Device address: 0005 (hex)
• Command code: 3005 (hex)
• Instruction code: 0101 (hex).
Assuming there is no error, the response is four bytes: 3005 0000 (hex).
Read Mini FINS Command
The Read mini FINS command consists of
• A device address number.
• A command code MRC/SRC.
• A variable area type, indicating the area within the device, from where the
parameter must be read.
• A Read start address within the specified area.
• A Bit position within the parameter to be read.
• The Number of bits/bytes to read from the parameter area/location.
