Signal name Description
X5
Information linkage
status
(1) Turns ON when the MES interface function operation is enabled.
This indicates that MES interface function processing is executable.
(2) Turns OFF when the MES interface function is in stop.
The MES interface function processing stops in the following cases.
1) The period after the programmable controller is powered ON from OFF or the programmable
controller CPU is reset until the MES interface function starts
2) When the MES interface function processing stops with [Remote operation] of MES Interface
Function Configuration Tool ( Section 7.13 Online - Remote operation)
3) When a module stop error occurs in the MES interface module
( Section 10.3.1 When using MES Interface Function Configuration Tool)
4) During updating settings ( Section 7.13.2 Manipulating the operation status of the MES
interface function)
5) While file access is stopped ( Section 4.7 CompactFlash Card)
XB
SNTP time query
timing
(1) Turns ON when [Synchronize with SNTP] is selected in [Time synchronization setting], and
after succeeding the time query and storing the time into the buffer memory.
(2) Reads time data from the SNTP time query results (Buffer memory address: 11501 to 11507),
while XB is ON.
(3) This device turns OFF 1 second after XB turns ON.
X10 ERR. LED status
(1) Turns ON while the ERR. LED is ON (during a module continuation error) or flashing (during a
module stop error).
(2) Turns OFF when the ERR. LED is turned OFF by turning the Error clear request (Y10) ON with
the ERR. LED ON. (However, this is not possible while the ERR. LED is flashing.)
(3) While the ERR. LED is ON or flashing (when X10 is ON), any or some of X11, X12, X16, and
X1C turn(s) ON.
X11 Sampling error
(1) Turns ON when an error regarding Sampling error occurs.
(2) When this device is ON, the error code is stored into the Tag status area (Buffer memory
address: 1000 to 1075).
(3) Turns OFF when the Error clear request (Y10) is turned ON.
X12
Information linkage
error
(1) Turns ON when an error regarding information linkage occurs.
(2) When this device is ON, the error code is stored into the Error log area (Buffer memory
address: 150 to 247).
(3) Turns OFF when the Error clear request (Y10) is turned ON.
