DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a terminal device according to the present invention is shown in FIG.
~ It will be described in detail with reference to FIG. 1 is a block diagram showing a terminal device, FIG. 2 is an image diagram showing a table format of a storage unit, and FIG. 3 is a front view showing an outline of the terminal device.

As shown in FIG. 1, the terminal 1 comprises a mother board 10, a CPU unit 11, and a monitoring input unit 12. Further, the terminal device 1 is connected via a signal line L to a monitor control device A corresponding to a host. The motherboard 10 has a total of 15 slots. The CPU unit 11 is a unit that is inserted into the first slot of the mother board 10 and includes a transmission unit 11a, a central processing unit 11b, a program storage storage unit 11c, and a data storage storage unit 11d. The monitoring input unit 12 is a unit that is inserted and attached to the second and subsequent slots of the motherboard 10, and has two common terminals T _c, T _c corresponding to the input section and 16 non-voltage a-contact input terminals T _0, ... with T ₁₅ .

The transmission section 11a exchanges various data with the monitoring control apparatus A via the signal line L under the instruction of the central processing unit 11b. The central processing unit 11b executes an operation based on the program stored in the program storage storage unit 11c, and controls the entire terminal device 1.
The program storage / storage unit 11c internally includes a state monitoring unit, an updating unit, a notification data setting unit, and a counting unit as software. Data storage storage unit 1
1d internally has a table format (shown in FIG. 2) for storing various data.

The state monitoring means sequentially scans the input states of the non-voltage a-contact input terminals T _0, ... T ₁₅ (whether or not they are short-circuited with the common terminal T _c ) corresponding to the input section, and outputs the scan results. Is the software to get. The updating means is a non-voltage a-contact input terminal T _{0, which} the state monitoring means sequentially scans _,
... an input state of the T _15, compared with the state of the "state" table corresponding to the state storage unit of the table format of the data storage memory unit 11d has already been written, if they differ in the data storage memory unit 11d table It is software that updates the states already written in the format's "state" table. The notification data setting means is based on a command signal output to the signal line L as an initialization process when the monitor control device A is powered on and started up. It is software that sets “valid” or “invalid” for each non-voltage a-contact input terminal T _0, ... T _{15 in the} table, and sets “type” or “number of state changes” in the “type” table. The counting means is
When the updating unit updates the state already written in the “state” table of the table format of the data storage storage unit 11d, the “state change count” table corresponding to the number storage unit of the table format of the data storage storage unit 11d. It is software that increments the number of state changes already written in.

The "terminal device address" table of the table format of the data storage / storage section 11d stores the address set by a dip switch (not shown) as the address of the terminal device 1. Data storage storage unit 11
The "slot number" table in the table format of d, non-voltage a contact input terminal T _0, ... T ₁₅ is monitoring the input unit is inserted into what number slot of the motherboard 10 12
A slot number for identifying whether or not the slot number is stored. The "port number" table of the table format of the data storage / storage section 11d stores the port number for specifying which of the non-voltage a-contact input terminals T _0, ... T ₁₅ is the input terminal. .

The terminal 1 configured as described above operates as follows. That is, the central processing unit 11b executes the state monitoring means, and, for example, the 1st port of the monitoring input unit 12 of the 2nd slot of the motherboard 10 (no voltage a
The input state of the contact input terminal T ₀ ) (whether or not it is short-circuited with the common terminal T _c ) is obtained. The central processing unit 11 which has acquired the input state of the 1st port of the monitoring input unit 12 of the 2nd slot
b compares the input state of the 1st port of the monitoring input unit 12 of the 2nd slot with the state stored in the corresponding "state" table of the data storage storage unit 11d, and if they match, The input state of the port 2 of the monitor input unit 12 of the slot 2 of the motherboard 10 is obtained, but if they do not match, the updating means is executed and stored in the corresponding "state" table of the data storage storage unit 11d. The state change count of the “state change count” table corresponding to the 1st port of the monitor input unit 12 of the 2nd slot in the data storage / storage section 11d is updated by rewriting and updating the state. After the increment, the input state of the port 2 of the monitor input unit 12 of the slot 2 of the motherboard 10 is obtained.

The central processing unit 11b performs the above-described operation on all terminals of the non-voltage a-contact input terminals T _0, ... T ₁₅ of the monitoring input unit 12 of the 2nd slot, and the monitoring input unit 12 of the 3rd slot. All terminals of non-voltage a-contact input terminals T _0, ... T _{15 ,} ..., monitoring input unit 1 of slot 15
The two non-voltage a-contact input terminals T _0, ... T ₁₅ are all cyclically and repeatedly executed.

Here, when the supervisory controller A makes a data request to the terminal 1 via the signal line L with an address, for example, the data of the port 1 of the supervisory input unit 12 of the slot 2 of the motherboard 10 is sent. Central processing unit 1 of container 1
1b recognizes the data request via the transmission unit 11a.
The central processing unit 11b recognizing the data request confirms the "valid / invalid flag" table of the first port of the second slot of the data storage / storage section 11d. The central processing unit 11b, which has confirmed the "valid / invalid flag" table, determines that the first port of the second slot is in use if the "valid / invalid flag" table is valid, and then the data The "type" table of the 1st port of the 2nd slot of the storage unit 11d is confirmed. The central processing unit 11b that has confirmed the "type" table indicates that the "type" table is "state".
If so, the status of the "status" table (for example, on / off)
If the “type” table is “state change count”, the number of times in the “state change count” table is recognized, and the recognized data is notified from the transmission unit 11a to the monitoring control apparatus A via the signal line L. .

Therefore, in the terminal device 1 as described above, the no-voltage a-contact input terminal T ₁₅ of the monitoring input unit 12 of the second slot of the terminal device 1 is unused, and the "valid / invalid flag" table However, if a load device that needs to count the number of state changes is to be added, for example, when the monitoring control device A sends the terminal device 1 to the data storage storage part 11d. The "valid / invalid flag" table of "No.", and the "type" table of the data storage storage unit 11d is set to "number of state changes".
By outputting the command signal to be set via the signal line L, the monitoring input unit 12 of the second slot of the terminal device 1 can be easily installed from a distance without going to the place where the terminal device 1 is installed. The voltage a contact input terminal T ₁₅ can be used as a port for notifying the monitoring controller A of the number of state changes. Similarly, the port can be simply notified of the status.
