U
Step 7 : Get POLL Info
This function is to obtain the device’s POLL information. After the slave
device responses the data, it will show in the “In” and “Out”. “In” means the
input length of the slave device. “Out” means the output length of the slave
device. If the slave device responses successfully, the return value will be 0.
U
Step 8 : Config POLL
If the step 7 is successful, the users can perform “Config POLL” button.
This function is to add the device’s POLL information into EEPROM in PISO-
DNM100. If it is successful, the return value will be 0.
U
Step 9 : Start Device
If the step 8 is successful, the users can perform “Start Device” button.
This function will communicate with the slave device which the users have
configured in the previous steps. If it is successful, the return value will be 0.
U
Step 10 : Read POLL Input I/O Data
If the master is communicating with the slave device successfully, the
users can read the input I/O data from the slave device in this step. This
function will obtain the input I/O data and show them in byte (8-bits). If the
users have 8 digits input, the return value will show 1 byte. Similarly, if the
users have 16 digits input, the return value will show 2 bytes. And so on.
