Note: When the IO unit is not assigned any address value, the mapped address is displayed as empty. When modifying the address of an IO unit, only eight input and output points of one byte (1 byte = 8 bits) can be set, and the address mapping of a certain bit cannot be modified individually.

4.2.2 988TA series standard ladder address setting

After the GSKLINK bus communication is normal, press the 2 level machine tool manufacturer level authority GSKLink→Unit 1/0→1/0 parameter→ Soft key, through modify The button can set the mapping address corresponding to each byte. According to the configuration of the standard ladder diagram, set as shown in Figure 4-2.

Figure 4-2

The system will list all the input and output points according to the current IO unit configuration. The input point is DI, the output point is DO, and the number of ports is allocated according to the number of input and output points. For example, the input points of the IO units that are adapted to the IOL-02T and IOR-44F are DI01 to DI48, and the output points are DO01 to DO32.

 Adapter IOR-44F

When the 988TA series CNC is equipped with the IO unit of the IOR-44F, the IO unit has 48 inputs and 32 outputs. The standard ladder configuration addresses in the system are X100 to X105 and Y100 to Y103. If you are using the system's standard ladder diagram, you must configure the IO unit according to the address defined by the ladder diagram. Since the IOR-44F is output by horn insertion, it is generally necessary to adapt a splitter like MCT07. The splitter is connected with the IO unit. The splitter is shown below.

The address assignment is shown in the following table.

 Input signal connection

There are two ways to input the external input signal: one uses a contact switch input, as shown in Figure 4-4.：

Figure 4-4 Contact switch input

The other uses a non-contact switch (transistor) input, as shown in Figure 4-5, Figure 4-6.

Output signal connection

 Output signal is high

The output signal is used to drive the relay and indicator on the electric line side of the machine tool or on the machine panel side. When the output is valid, the corresponding Y address output status is 1, the output interface potential is +24V; when the output is invalid, the corresponding Y address output status Is 0, The output interface behaves as a high impedance state. The circuit is shown in Figure 4-11.

Figure 4-11 Internal circuit structure of the output signal

Therefore, the output signal has two output states: +24V output or high impedance. Typical applications are as follows.

Ø Driving light emitting diode

The output drives the LEDs and requires a resistor in series to limit the current flowing through the LEDs (typically about 10 mA). As shown in Figure 4-12 below

Figure 4-12

Ø Drive filament type indicator

The output drive filament type indicator light needs to be connected with a preheating resistor to reduce the current impact during the conduction. The resistance of the preheating resistor is such that the indicator light is not bright, as shown in Figure 4-13.

Figure 4-13

Ø Driving inductive loads (such as relays)

The output drives the inductive load. In this case, a freewheeling diode needs to be connected near the coil to protect the output circuit and reduce interference. As shown in Figure 4-14

Figure4-13

Ø Driving inductive loads (such as relays)

The output of the IO unit of the IOR-44F signal is active high, using the above connection method, the connection diagram is as shown 4-15

Figure 4-15

 COM port connection

The COM terminal in the IOL-44F output port should be connected to 24V, otherwise it will not output high level.
