2. Programming Concepts
Output clear signals when ZRN is completed
Contents:
When M1346 = ON, PLC will output clear signals when ZRN is completed. The clear signals to Y0,
Y1 will be sent by Y4 for 20ms, and the clear signals to Y2, Y3 will be sent by Y5 for 20ms.

M1350-M1356, M1360-M1439, D1355-D1370, D1399, D1415-D1465, D1480-
D1991
Contents:
1. PLC LINK supports COM2 (RS-485) with communication of up to 16 slaves and access of up
to 50 words. (DVP-12SE V1.6 and DVP-26SE V2.0 can connect to up to 32 slaves, and
read/write up to 100 words.)
2. Special D and special M corresponding to Connection ID1~ Connection ID8: (M1353 = OFF,
access available for only 16 words)
Special D registers for storing the read/written 16 data (Auto-assigned)

Data length to be read/written for connections (Max 16 pieces of data; 0: no reading/writing)
Starting address of the Connection to be read, written or connected.*
M1355 = ON, Connection status is user-defined. Activate the Connection manually with M1360~M1367.
M1355 = OFF, Connection status is auto-detected. Monitor if the connection is established and activated with M1360~M1367
Communication status of Connection ID#1-8 on PLC LINK (ON: communicating)
Error flag for errors occurred when reading and writing (ON = normal; OFF = error)
“Reading completed” flag (System resets to OFF after reading is complete on one module.)
“Writing completed” flag (System resets to OFF after writing is complete on one module.)
