2. SYSTEM CONFIGURATION
This chapter describes the system configuration of the gateway functions.
2.1 System Configuration of Gateway Functions
When the gateway functions are used, one GOT connects to Ethernet and PLCs and therefore both the Ethernet communication module and communication board must be mounted to the GOT.
Hence, the gateway functions cannot be used for the GOT that cannot be mounted with the Ethernet communication module and for the connection form that uses the communication module.
(Example 1) For A951GOT
Since the Ethernet communication module cannot be mounted, the gateway functions cannot be used.
(Example 2) For CC-Link connection
Since two different communication modules cannot be mounted to one GOT, the gateway functions cannot be used.

5.5 Precautions
This section provides the precautions for using the server and client functions.
Precautions for assigning the devices in the gateway setting
(1) The gateway devices are set as at least two points, and set on a two point basis thereafter.
(2) When a bit device is assigned, 32 points are set, starting from the set device.
(3) When a device was not assigned, the unassigned area (empty area) is on a word basis.
(4) The network number and PLC station number must be set to assign the MELSEC-A/QnA/Q series PLC CPU devices.
(5) The CPU number must be set to assign the CPU of the multiple PLC system.
(6) If station No. is changed while monitoring the gateway device to which PLC CPU device has been assigned,the monitored device is irrelevant to the station No. change.
Example) When station No. is changed on the GOT (server)
GD100(D100) D100 250
GOT(Client function) GOT(Server function)
Use the script function to read EGO to the GOT internal device.

Station No.2 Station

If station No. is changed on the GOT (server), the station No. change is irrelevant to the GOT (client) that monitors D100 assigned to the gateway device.
As D100 has not been assigned to the gateway device on the GOT (server), station No. change is executed.

Precautions for setting the script function
(1) When setting the script function, do not set the trigger type to [Ordinary] or [Sampling, within 2 seconds].
Doing so may affect the other monitor operations.
(2) The script function cannot be used to monitor the gateway devices of the GOT itself.
When monitoring the PLC devices assigned to the gateway devices, monitor the PLC devices directly.
Precautions for using GT Simulator for debugging
(1) GT Simulator cannot debug the gateway functions.
An error will occur if the gateway device is monitored or data is written to the gateway device.
Precautions for monitoring
(1) If the GOT monitors devices by transient communication via the network, the monitor speed will decrease.
To increase the monitor speed, use link devices.
(2) If the gateway device of the GOT of the server function is monitored in a status where the server and client functions cannot be used , an error occurs and the script stops.
While power is off, when the ROM_BIOS version of the GOT is incompatible, or when the memory board is not fitted, for example.
(3) The gateway device, to which the PLC device has not been assigned, is monitored as 0 (OFF for bit).
When write is executed, the written value is invalid.
(4) If the screen save of the GOT is canceled (by a screen touch or the human sensor) during execution of the script that uses the gateway devices, it may take some time to cancel.
When the execution of automatic screen save has been specified, it may take more time than the specified.
(For example, when the script processing time is 2 seconds, the screen save is canceled in a
maximum of 2 seconds after the screen is touched.)
5.6 For Efficient Use
This section explains the points for efficient use of the server and client functions.
Script function setting
When the gateway devices are used directly to execute a program, the number of times to access the other GOT increases, slowing the processing.
By performing batch read from the GOT internal devices and performing batch write after execution of the processing as shown in the following (1), the number of access times can be decreased, improving the processing speed.
(1) When performing batch read from GOT internal devices (GD) and performing batch write after processing
Access to the other station GOT occurs twice (1), 3)).
When one time of access requires 50ms, the necessary processing time is about 100ms.

Access to the other station GOT occurs 10 times (1) to 10)).
When one time of access requires 50ms, the necessary processing time is about 500ms.

Point About the written values
In the above (1), the gateway devices are batch-accessed when the script execution
condition is established. Therefore, the gateway device values available when the
Gateway device setting
When assigning the PLC devices to the gateway devices, set the same type of devices of the same PLC together where possible.
By setting the same devices of the same PLC together as in the following (1), the number of access times can be reduced, improving the processing speed.
(1) Devices of host, other station and other PLC are set together
When the GOT of the client function accesses the host devices of the GOT of the server function, access can be made with the program that reads 50 points starting from EG0 (1)).
Script description example 1) bmov([W:GD100], [1-2:w:EG0],50);
(2) Devices of host, other station and other PLC are set not together
When the GOT of the client function accesses the host devices of the GOT of the server function, access requires the program that reads 40 points starting from EG0 (1)) and the program that reads 10 points starting from EG130 (2)).
Script description example 1) bmov([W:GD100], [1-2:w:EG0], 40);
2) bmov([w:GD140], [1-2:w:EG130], 10);
