*1 External input request to the sensor amplifiers connected to the DL-PN1 (Slot 0) can
be executed en bloc. (Smart Access function)
Functions assigned to the external input request 1 to 4 are as follows:
• External input request 1: PRESET input
• External input request 2: TIMING input
• External input request 3: RESET input
• External input request 4: ERROR CLEAR input
Refer to the GT2 series user's manual.
 Sensor amplifier (Slot 1 to 15)
 Output
Functions assigned to the external input request 1 to 4 are as follows:
• External input request 1: PRESET input
• External input request 2: TIMING input
• External input request 3: RESET input
• External input request 4: ERROR CLEAR input
Refer to the GT2 series user's manual.
 Communication Methods
The following describes how the I/O controller communicates with the DL-PN1 (data I/O
communication).
• "Reading an output from a sensor amplifier" (page 8)
• "Entering an external input to a sensor amplifier" (page 8)
• "Reading comparator values (P.V. values) from sensor amplifiers" (page 9)
