7 APPLICATION FUNCTIONS
Setting data
Setting data 3 4
Jn Network No. of the target station (1 to 239)
Target station No.
Specify the station No. of the target station.
1) Station No. specification
1 to 64: Station No.
2) Group specification
n1
81
H
3) All stations specification
FF
H
When a group is specified, set the group No. of the target station with the network
parameters from GX Developer.
Target station's start device to which data are to be written.
(D1)
(A contiguous area for the write data length is required.)
(S1) The host station's start device where write data are stored.
Write data length
n2 When the target station is Q/R/L/QnA/AnUCPU: 1 to 230 words
When the target station is other than Q/R/L/QnA/AnUCPU: 1 to 32 words
The host station's device that is turned on for one scan upon completion of the instruction
(D2)+1 also turns on if the instruction execution is failed, and the error code is stored in
(D2)
the SW0033.
(For the error code, refer to Section 8.3.)
3: Local devices and file registers for each program cannot be used as devices in setting data.
4: The ZNWR instruction is executed using the following fixed values as well as setting data.
Channel used by host station: Channel 2
Arrival monitoring time (monitoring time until instruction completion): 10 seconds
Number of resends for arrival monitoring timeout: 0 times
5: The setting side is as shown below.
User : It is data the user sets in the sequence program before execution of a link dedicated instruction.
System: The programmable controller CPU stores the execution result of the link dedicated instruction.
7 - 85
to A0 : All stations of a group (No.1 to 32)
H
: All stations of the target network No. (Except the host station)
POINT
(1) Specify the device of the other station CPU module to be written with the
ZNWR instruction within the range available for the host CPU module.
(Head device No. (D1) of write target of other station CPU module) +
(Number of write points - 1)
: Last device number at the host CPU module having the same device
name as (D1)
(2) When a CPU module on another station written by the ZNWR instruction is an
A2UCPU(S1), A3UCPU, A4UCPU, A2ASCPU(S1), or A2USCPU(S1), use
the CPU module with the following version or later.
• A2UCPU(S1), A3UCPU, A4UCPU: Version AY (manufactured since July,
1995) or later
• A2ASCPU(S1), A2USCPU(S1): Version CP (manufactured since July,
1995) or later
