$Pn: 508 to 511
If "800BH" is stored for the error status information ($Pn: 100 to 355), on transferring the data of that station number to any
internal device memory address, the reception code will be obtained at $Pn: 508 to 511.
Notes on use
 Use $u/$T as the target internal device memory.
 Use the macro command MOV (W). MOV (D) cannot be used.
 "0" is stored to device memory addresses that have no expansion error code.
 Example PLC2: Fuji Electric PXR station No. 1
1) On receipt of an error code at station No. 1 of PLC2, "800BH" is stored in $P2:101.
PLC1
2) The data of $P2: 101 is transferred to $u1000 by a MOV command.
$u1000 = $P2: 101 (W)
PLC1
3) The reception code is stored in $P2: 508.
$P2:508 = 0002H
PLC1
4) The PXR manual shows that code 002H means "device memory address range exceeded".
Amend the screen program address designation.
