*15 In order to apply the settings of data category N x 10 +4 Data Nos. 76 to 79 to
the sensor amplifier, either Data No. 75 must be set to "1 (user setting)", or the
sensor amplifier operation buttons must be used to specify the "external input"
setting as "user setting".
*16 An ASCII character string is sent back in response data (4 bytes). The data
types is DINT.
For "SK-1", the response is "534B2D31h".
*17 The read value of the two-digit value can be translated to a binary number, so
that the ON/OFF state of each bit can be noted to know the status of judgment
output and check output.
Assume the read data is "05":
Translating "05" to a binary number gives "0101".
N.O. mode
*18 The external input status is "1" when the external input is ON, and is "0" when
the external input is OFF. Bits 0, 1, 2, and 3 correspond to external inputs 1, 2, 3,
and 4, respectively.
Assume the read data is "06":
Translating "6" to a binary number gives "0110".
*19 An ASCII character string is sent back in response data (16 bytes). The data
types is STRING.
For "SK-1000", the response is "534B2D31303030000000000000000000".
