• Even addresses must always be used for indirect addressing (@∫0001, @b0173, etc. are
prohibited).
• For details of indirect addressing, see PC's programming manual.
• F-205 instruction must always be used in conjunction with the F-202 (OPCH) instruction.
• After turning ON the input signal of F-205, keep it ON until the finish of the execution of the
instruction. If the input signal is turned OFF during execution of the instruction, the instruction
13
ends in an incomplete condition. Under this condition, next, when an F-205 instruction is given, it
will come to a "communication jam," and the instruction will not be executed. Turn the power OFF
and then ON again for recovery.
[*1]
Setting range of "S" is for JW model PCs. For ZW model PCs, setting range is ｺ0000 to
19777.
[*2]
In case that the network module of the assigned module number is not installed.
[*3]
In case that the channel is used with the other SEND/RECEIVE instruction.
This instruction is executed after end of execution of the previously given instruction, and
flag sign is changed into "communication busy" from "communication jam."
[*4]
In case that response from target station does not come within the time-out time.

When the input condition of 14003 changes from OFF to ON,
this instruction reads 6 bytes of data from file 0's file area
beginning with file address 04000 on satellite net station 04,
via CH0 of port No. 2. The data read is stred to registers
19000 to 19005.
