Graphic Operation Terminal F940GOT Sampling Mode 5
5-12
5.5 Control signals in PLC
The sampling data can be cleared and the sampling status can be monitored from the PLC
without manipulating the GOT.
5.5.1 When screen creation software DU/WIN is used
• Eight auxiliary relays (M) are occupied for communication between the GOT and the PLC.
They are called control devices, and M0 to M7 are assigned (For the details, refer to Para-
graph 9.6.).
• When the screen creation software is used, device Nos. M0 to M7 can be changed.
• In the sampling mode, M3 and M4 are used.
Example: When the head control device No. is set to M0
M3: Clears the sampling data. (It is used as a coil.)
M4: Remains ON while sampling is performed. (It is used as a contact.)
5.5.2 When screen creation software GOT-A900 is used
• Word devices are occupied for communication between the GOT and the PLC. (Refer to
Paragraph 9.6.2.)
• Read devices and write devices are set for communication, and the following devices are
used in the sampling mode.
Read device : When the third bit (b2) of the specified word device becomes ON, the sam-
pling data is cleared.
Write device : The second bit (b1) of the fifth word device from specified word device (which
is regarded as the first word device) remains ON while sampling is per-
formed.
M3
Sequence program
When the contact input becomes ON,
the sampling data is cleared.
M4
When M3 becomes ON during sampling, sampling is aborted and the acquired data is
cleared. It is recommended to provide a b contact of M4 for interlock so that the acquired
data is not cleared during sampling.
M8000 (always ON)
MOV D10 K1M10
MOV D24 K1M20
M21
M12
Remains ON while
sampling is performed.
Clears the sampling data when the contact input becomes ON.
The bits of the specified read device
(D10) are developed to M10 to M13.
The ON/OFF information of D24
(= specified read device D20 +5 ) is developed to
M20 to M23.
M21: Remains ON while sampling is performed.
M12: Clears the sampling data.
Example: When D10 is assigned as a read device and D20 as a write device
