3-3 Communication Methods

Communicating with the FD-S series

Available motion commands: See "Motion command parameters" (page 3-25).

Commands can be used to reset preset values, clear errors, or for other purposes.

To issue a motion command to a sensor amplifier, create a program that controls

commands by handshaking between a remote input/output and remote register

This example executes integration reset on ID 01.

(1) To see that the sensor amplifier is ready to send/receive commands, check that the "sensor ready"

parameter is set to 1.

(2) Write the data category and command number in the remote register.

Data category: For motion command, write 00h in the high byte.

Data number: For motion command, write 02h in the low byte.

(3) Write the data number in the remote register

ID number:

In the high byte, write the ID number of the sensor amplifier to which to issue the motion

command.

Data number: In the low byte, write the data number of the intended motion command, by referring

to "Command Parameter List" (page 3-24).

(4) Execute the motion command by activating the "request for command" (0 -> 1).

(5) After the command execution on the sensor amplifier completes, the "command completed" signal

flips from 0 to 1.

(6) If an error occurs during command ex

ecution, the "command error" signal flips from 0 to 1. For

details of the error, check the values entered in the "command response".

(7) Details of the command execution result are stored. For details of the result, see "Command

response list" (page 3-8).

(8) When the "request for command" is set to 0, the "command completed" and "command error"

parameters flip to 0.
