Explanation
Transmission
input/output signal data
designation
SendIOType
unsigned short
(2-byte)
1) When transmitting (commanding) from the personal computer to the
controller, designate the data type of the input/output signal transmitted
from the personal computer.
Designate "No data" when not using this function.
2) When receiving (monitoring) from the controller to the personal
computer, this indicates the data type of the input/output signal replied
from the controller.
The contents of the data are common.
0 // No data
1 // Output signal
2 // Input signal
Reply input/output
signal data designation
RecvIOType

(2-byte)
1) When transmitting (commanding) from the personal computer to the
controller, designate the data type of the input/output signal replied from
the controller.
Designate "No data" when not using this function.
0 // No data
1 // Output signal
2 // Input signal
2) When receiving (monitoring) from the controller to the personal
computer, Not used.
Input/output signal data
BitTop
BitMask
IoData
unsigned short
unsigned short
unsigned short
(2-byte x 3)
1) When transmitting (commanding) from the personal computer to the
controller, designate the output signal data transmitted from the personal
computer.
2) When receiving (monitoring) from the controller to the personal
computer, this indicates the input/output signal data replied from the
controller.
The contents of the data are common.
BitTop; // Head bit No. of input or output signal
BitMask; // Bit mask pattern designation (valid only for
commanding)
IoData; // Input or output signal data value (for monitoring)
Output signal data value (for commanding)
* Data is 16-bit data
Timeout time counter
value
Tcount
unsigned short
(2-byte)
1) When transmitting (commanding) from the personal computer to the
controller, Not used.
2) When receiving (monitoring) from controller to personal computer, if the
timeout time parameter MXTTOUT is a value other than -1, this indicates
the No. of times communication with the controller was not possible. When
the No. of times is counted and reaches the maximum value, the value will
return to the minimum value 0, and the count will be repeated. This is set
to 0 when the MXT command is started.
Counter value for
communication data
Ccount
unsigned long
(4-byte)
1) When transmitting (commanding) from the personal computer to the
controller.
2) When receiving (monitoring) from controller to personal computer, this
indicates the No. of communication times.
