The function of DL-DN1 only, which responds to explicit messaging synchro-
nously with I/O communication. This function does not guarantee synchronism
of the whole system, including PLC or master equipment.
Command Parameter List for FD-MH Series
The following tables provide command parameters for the FD-MH series. The two
types of parameters are: motion command parameters and setting/status command
parameters.
Motion command parameters
For the communication methods using motion command parameters, see
a Motion Command to a Sensor Amplifier" (page 3-19).

Current value
"over"
If instantaneous flow rates from
sensor amplifiers (ID 01 to ID 10) are
"over" (FFFF), they are output by
assigning them to bits 0 - 9.
