3.2 System monitor function specifications POINT
Refer to Section 2.3 for restrictions on the system monitor function.
3.2.1 PLC CPUs to be monitored
The PLC CPUs that allow system monitoring are the QCPU, QnACPU, ACPU, FXCPU and motion controller CPU. For details, refer to Section 2.3 (2).
3.2.2 Access ranges to be monitored
For access range for the system monitor function, see GOT-A900 Series User’s manual (GT Works Version5/GT Designer Version5 compatible Connection system manual).
3.2.3 Names of devices to be monitored
For the names of devices that can be monitored with the system monitor function, see GOT-A900 Series User’s manual (GT Works Version5/GT Designer Version5 compatible Connection system manual).
3.2.4 Precautions when using the system monitor function
The precautions to follow when using the system monitor function are shown below.
(1) Monitor and test of real number data
Real number data cannot be monitored or tested.
Monitoring of word devices that save real number data is all done by integer data (binary data).
(2) Monitoring in 32-bit modules
When monitoring word devices (such as T, C, D, W) in 32-bit (2-word) modules, monitor up to the point where 32 bits remain in the monitor processing. A location where 16 bits (1 word) remain cannot be monitored.
This situation occurs when an odd number has been specified as the initial number in the monitor device.
(Example) When monitoring the A2NCPU data register in 32-bit modules beginning with an odd number (D1, D3...)

3.3.4 Precautions when using the special module monitor function
The precautions to follow when using the special module monitor function are discussed below.
(1) Special function modules that cannot be monitored
Modules displayed as "special" on the system configuration screen cannot be monitored using the special module monitor function.
To monitor these modules, use the system monitor function "BM Monitor".
(2) Display when connecting the small building-block type PLC CPU
This precaution pertains to a situation where an expansion base unit for a large building block type of setup is connected to a small building-block type CPU (such as the A1SCPU) in a station connected to the GOT.
In such a case, the special function module on the large expansion base unit is displayed on the system configuration screen with the same model name as that of the small building-block type special function module.
If there is no small building-block type special function module, "special" is displayed and the object module cannot be monitored.
(Example)
[Module Model] [Model Name Displayed]
AD72 A1SD71
AJ71ID A1SJ71ID
AJ71PT32-S3 A1SJ71PT32-S3
AD75P A1SD75P
A68AND [CH1 to CH8] A1S64AD [CH1 to CH4]
A68RD [CH1 to CH8] A1S62RD [CH1 to CH4]
(3) Monitoring restricted special function modules (a) When monitoring the AD71 (S1, S2, S7)
When the slot on front of the AD71 module is an empty slot, monitoring is done in the following way.
1) The AD71 is treated as the AD72, and "AD72" is displayed on the system configuration screen.
In this case, when monitoring the AD71, select the AD72 in the object display position.
2) The monitor screen that is displayed by 1) above is for the AD72.
The number obtained by subtracting 10H from the I/O signal number on the display is the number to be used when installing the AD71 in the 0 slot.
∗ If you do not want the AD1 to be treated as the AD72, execute "Shift the installation position of AD71 forward" or "In the I/O assignments, assign the empty slot in front of AD71 to the 16 X-Y points."
(b) When monitoring the A68AD, A68ADN or A68RD used with a small building block type PLC CPU
A special function module installed in a large building block type extension base unit connected to a small building block type PLC CPU (e.g. A1SCPU) is recognized and monitor-processed by the GOT as a small building block type special function module. Hence, there are the following instructions for use of the A68AD, A68ADN and A68RD.
Special function module Instruction
A68AD
The A68AD cannot be displayed correctly because of the buffer memory map differences between the A68AD and A1S68AD.
A68ADN Among CH1 to CH8 of the A68ADN, CH5 to CH8 cannot be displayed since the A1S64AD has only CH1 to CH4.
A68RD Among CH1 to CH8 of the A68RD, CH3 to CH8 cannot be displayed since the A1S62RD has only CH1 and CH2.
The above special function modules can be monitored properly if they are installed in a base unit connected to a large building block type PLC CPU (e.g.
AnUCPU)
(c) When monitoring the A1SD75M, AD75M
The A1SD75M/AD75M is displayed as A1SD75P/AD75P.
The A1SD75M/AD75M can be monitored within the monitoring range of the A1SD75P/AD75P.
(d) When monitoring the A81CPU
The A81CPU is monitored in the following way.
64 points in first half 64 points in last half Treatment of A81CPU Change to module that cannot be
monitored. Change to input module.
System configuration
screen Display "Special X, Y " Display "Input 64 X "
Possibility of monitoring Not possible Can be monitored as input.
(e) When monitoring an I/O composite module
1) With an I/O composite module for which "Output " is displayed on the system configuration screen, only the output signal can be monitored.
For the input signal, monitor X of the PLC CPU device with the system monitor function.
(4) Editing and allocating of special module monitor data
Data displayed on a special module monitor screen cannot be edited by modifying or adding an object, except that the data can be used on a user-created monitor screen.
(5) Precaution for I/O allocation setting
(a) When the QnACPU is connected, the head XY numbers are displayed in due order on the special module monitoring system configuration screen if the I/O allocation setting is random as shown below.
When performing special module monitoring, always perform the I/O allocation in order from slot 0.
Input
Head XY number Slot number
Set randomly
0 20 40 60 80 A0
Module name not displayed.
GOT system configuration screen Input
Special Special Input
(b) If the slot assigned to Output in I/O allocation is not fitted with a module, the GOT displays Input. (Common to ACPU and QnACPU)
(6) The system configuration including remote I/O stations cannot be monitored.
(7) Display provided when the QA1S6 extension base unit is used with the QCPU(Q mode)
The following instruction is given for the case where the QA1S6 extension base unit is connected to the QCPU(Q mode) which is a GOT-connected station.
In this case, any of the following special function modules is displayed as the abbreviated formats on the system configuration screen.
You can use the Unit datail infomation to confirm the formal format of the module which was displayed as the abbreviated format.
Unsupported special function modules are displayed as "Special" and the corresponding modules cannot be monitored.
