RTWRITE
8.2.2 Registering routing information (S(P)/Z(P).RTWRITE)
RTWRITE
Function
(1) Registers routing data of or later in the area for the transfer destination network number
specified by n in the routing parameters.
(2) The following shows the contents of data to be set at or later.
(3) If data for the transfer destination network number specified by n is set in the routing
parameters, it is used to update the data in the area starting from .
(4) If all data in or later ( +0 to +2) is 0, the data for the transfer destination network
number specified by n is deleted from the routing parameters.
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and
an error code is stored into SD0.
• When data specified by n is other than 1 to 239. (Error code: 4100)
• When the data of or later exceeds each setting ranges. (Error code: 4100)
• When the total number of routing information registered in the routing parameter of the
network parameters and routing information registered with the RTWRITE instruction
exceeds 64. (Error code: 4100)
• The device specified by exceeds the range of the corresponding device.
(For the Universal model QCPU only.) (Error code: 4101)
n : Transfer destination network No. (1 to 239) (BIN 16 bits)
: Head number of the devices where the data to be written is stored (Device name)
