(d) Application example of channels
• Simultaneous access to other stations from the own station
Use a different own station channel for each request destination.
Channel 1: Write to station No.1
Channel 2: Write to station No.2
• Mutual access between the own station and another station
Use a different own station channel for each link dedicated instruction.
Channel 1: For send
Channel 1: For receive
The channel used for the RECVS instruction cannot be used for other instructions. Use a different channel for other
instructions.
(2) Executing link dedicated instructions to AnUCPU stations
(a) Executing an instruction to AnUCPU stations
Never execute a master/local module dedicated instruction to AnUCPU stations.
Doing so will cause "MAIN CPU DOWN" or "WDT ERROR", and may result in an operation stop in the
AnUCPU.
(b) Executing an instruction to all stations on a network that contains an AnUCPU
station
Use the group specification to exclude the AnUCPU.
(3) Executing link dedicated instructions to group-specified or all-specified
stations in a multiple CPU system
The instruction can be executed to only the control CPUs of the stations. Specify 0000
station's CPU type ((S1)+3) of the instruction.
