Notification before use

Depending on the type of product you are using, the definitions of ‘Parameter’, ‘IO Logic’, ‘AxisStatus’, etc. may be different. This example is based on ‘Ezi-SERVO’, so please apply the appropriate value depending on the product you are using.

Example)

FM_EZISERVO_PARAM           // Parameter enum when using 'Ezi-SERVO'    
FM_EZIMOTIONLINK_PARAM      // Parameter enum when using 'Ezi-MOTIONLINK'

1. Get IO level

bool GetIOLevel(int nPortID, unsigned char iSlaveNo)
{
    unsigned int uIOLevel = 0;
    bool bLevel;

    printf("---------------------------------- \n");
    // [Before] Check IO Level Status
    if (FAS_GetIOLevel(nPortID, iSlaveNo, &uIOLevel) != FMM_OK)
    {
        printf("Function(FAS_GetIOLevel) was failed.\n");
        return false;
    }
    printf("Load IO Level Status : 0x%08x \n", uIOLevel);

    for (int i = 0; i < 16; i++)
    {
        bLevel = ((uIOLevel & (0x01 << i)) != 0);
        printf("I/O pin %d : %s\n", i, (bLevel) ? "High Active" : "Low Active");
    }

    return true;
}

[EN]
With FAS_GetIOLevel() function, you can read the level information for each IO Pin. IO level information is written sequentially from LSB to MSB of uIOLevel. For example, IO level information of pin 0 is written in the LSB, and IO level information of pin 31 is written in the MSB. 0: Low Active Level / 1: High Active Level

FAS_GetIOLevel() 함수를 사용하여 각 IO Pin에 대해 설정된 Level을 읽을 수 있습니다. uIOLevel의 LSB에 0번 Pin의 Level부터 MSB에 31번 31번 Pin의 Level이 순차적으로 쓰여집니다. 0: Low Active Level / 1: High Active Level을 의미합니다.

    ~~ Fastech's product which has Input (or Output) only (Ezi-IO-I16, Ezi-IO-O16, Ezi-IO-I32, Ezi-IO-O32...), BitMask of Input (or Output) starts from 0x01,   ~~
    ~~ However, for Input+Output mixed products (Ezi-IO-I8O8, Ezi-IO-I16O16, etc.), the BitMask of Output is allocated after the BitMasks of Input.             ~~
    ~~ Ezi-IO-I8O8, for example, the BitMask of Input 0 is 0x0001, and the BitMask of Output 0 is 0x0100.                                                       ~~

    ~~ Input+Output 혼합 제품 (Ezi-IO-I8O8, Ezi-IO-I16O16 등)은 Input의 BitMask를 전부 할당한 뒤, Output의 BitMask가 이어서 할당되어있습니다.                      ~~

[EN]
You can set the level for each IO Pin using the FAS_SetIOLevel() function. IO level information is written sequentially from LSB to MSB of uIOLevel. For example, IO level information of pin 0 is written in the LSB, and IO level information of pin 31 is written in the MSB. 0: Low Active Level / 1: High Active Level. The source code above sets Pins 0 to 7 to Low Active Level and Pins 8 to 15 to High Active Level. (16 Pins)

[KR]
FAS_SetIOLevel() 함수를 사용하여 각 IO Pin에 대해 Level을 설정할 수 있습니다. uIOLevel의 LSB에 0번 Pin의 Level부터 MSB에 31번 31번 Pin의 Level을 순차적으로 입력합니다. 0: Low Active Level / 1: High Active Level을 의미합니다. 위 소스 코드는 0~7번 Pin을 Low Active Level로, 8~15번 Pin을 High Active Level로 설정합니다. (16 Pin)
