Communicating with the FD-MH series
- CC-Link Compatible Network Unit DL-CL1 User’s Manual (FD-MH) -
Select an operating mode of the DL-CL1 to suit the functions of the sensor amplifiers
to be used.
The  specific CC-Link device configu ration  and the data that can  be communicated
using cyclic transfer vary with each operating mode of the DL-CL1. An appropriate
operating mode should  be determined by considering the number of link points the
data that can be communicated.
 "Configuring the Data Link" (page 2-
10)
Ye s: Available with sensor amplifiers of ID 01 to 10. No: Not available.
*1 For details of the functions assigned for motions commands and setting/status read/write, see  
"Device Maps" (page 3-4) and  "Command Parameter List" (page 3-24).
*2 In remote register RWw, specify the ID number of the sensor amplifier from which to read.
*3 To use this communication method, crea te a program that controls commands by handshaking 
between a remote input/output and
 remote register.
*4 It is possible to read instantaneous flow rate or rewrite setting value regardless of the detection 
mode setting.
