(6)   Program example 

(a)   Interlock program example for remote master station and 

remote I/O station 

Provide interlocks depending on the link status of the remote master station 
(local station) and remote I/O station (other station). 
The following example shows communication program interlocks using the 
link status (SB47, SB49) of the remote master station and the link status 
(SW70 bit 0, SW74 bit 0, SW78 bit 0) of the remote I/O station (station No. 
1). 

 

Program for automatic communication function: Refer to (b) in this section.

SB47: Baton pass status(host) 

SB49: Host data link status

SW70: Baton pass status of each
            station

SW74: Cyclic transmission status
            of each station

SW78: Parameter communication
            status of each station

SB20: Module status

 

 

Set the following value in the timer constant K . 

 

Baton pass status 

(T0, T2) 

(Sequence scan time   4) or more 

Cyclic transmission status 

Parameter communication status 

(T1, T3, T4) 

(Sequence scan time   3) or more 

Reason: To prevent control from stopping even if the network detects an 

instantaneous error due to a cable problem, noise or other condition. 
Note that "  4" and "  3" represent standard values. 

 

POINT 

 

For details of the interlock program for the remote master station and remote I/O 
station of MLESECNET/H, refer to the "Q Corresponding MELSECNET/H Network 
System Reference Manual (Remote I/O Network)".
