    +10V- +30V. Connecting the communication line: DAM-3028MC is connected to computer through RS485 bus. Restore factory settings: In the case of power failure, short-circuit INIT* and GND, the module indicator flashes rapidly 3 times after power-on, and after the flashing stops, disconnect the short-circuit wire, power on again, and the module is reset.
  • Page 28 Figure 10 Click the module information to display the configuration information interface, double-click the module address information on the left, the following interface will appear, then change the baud rate, address, parity of the module, click the modify button to complete the communication port configuration, and search for the module again.
  • Page 29 The corresponding configuration is completed when the search is successful. DI working mode: DI input, count, low to high latch, high to low latch, frequency. Figure 12 ① DI input: The input state changes in real time. If input low level (0~+3V or ground), the input status is green, and it input high level (+10V~+30V or open circuit) , the input status is red.
  • Page 30 Figure 13 ② Counting: The counting frequency is 0~400HZ, the initial value of the count is the initial accumulation value, and the accumulation starts from 0 by default, and the maximum count value is 4294967295. The overflow flag is displayed as 1 after exceeding, and the exceeding value will be accumulated from 0.
  • Page 31 ④ High to low latch: When the input high level changes to low level, the latch state turns red, the input state is low level, and the latch state can be cleared. The reverse signal is the same as the DI input. Figure 15 ⑤...
  • Page 32 ① Immediate output: The host computer controls the output state, and the module responds immediately, that is, the host computer control output and the module output state are synchronized, and the cycle is consistent. Figure 17 ② Low to high delay output: Change the output state after setting the delay time. When the output is from low level to high level, the output signal time will be extended according to the set parameters.
  • Page 33 When only "Add Count" is set and click "Add", the module only outputs the added pulse count. Just click the output status icon, the module will output a complete pulse according to the set output parameters. Just click the pulse output stop button, the module will output a complete pulse according to the set output parameters.
