Wait Flag Board:
CIO 190909 (port 1)
CIO 191909 (port 2)
Unit:
n + 9 bit 09 (port 1)
n + 19 bit 09 (port 2)
This flag is turned ON when a sequence is
waiting due to the WAIT command. Waiting
is released when the Wait Release Switch is
turned ON in the ladder program, and the
sequence will move to the next step.
Make sure to set the Wait Release Switch
from the ladder program to turn ON the
switch. If the Forced Set Key on Program-
ming Console is used, the Wait Release
Switch will remain ON, and may stop the pro-
tocol macro function from being able to turn
OFF the flag.

This flag is turned ON when the Serial Gate-
way (mode) is prohibited due to the status of
the Serial Gateway Prohibit Switch in the
user program. This flag turns OFF when the
Serial Gateway is not prohibited. Startup When

The list of error codes is provided at the end
of this table on page 175.
If a Serial Communications Board is used
and either error code 3 (data read/write area
exceeded error) or 4 (protocol data syntax
error) is stored, A4241 (protocol macro syn-
tax error) will be turned ON, the ERR/ALM
indicator on the CPU Unit will flash, and a
non-fatal error will occur. If a Serial Commu-
nications Unit is used, the ERC indicator will
flash. Only error codes 0, 2, 3, and 4 are
used.
When an error occurs, the error code is held
until the next sequence starts.
The error code is cleared when the
STUP(237) instruction is executed, when the
Unit/Board is restarted, or when the next
sequence execution starts.
When a Board is used, clear the non-fatal
error resulting from error codes 3 and 4 by
removing the cause of the error, and then
clear the error display by executing the next
sequence or the STUP(237) instruction, by
restart, or by switching the CPU Unit to PRO-
GRAM mode.

The current communications sequence num-

starts. This number does not change when a

occurs. Startup
