    The data conversion between PROFINET network and serial of GT200-PN-RS is established by "mapping". GT200-PN-RS has two data buffers, one is input buffer (1K bytes) with address range 0x0000-0x03FF; the other is output buffer (1K bytes) with address range 0x4000-0x43FF.
  • Page 14 0x0000-0x03FF and 0x4000-0x43FF and send data to the serial slave device. When serial slave devices didn't give any response (if they did), if there exists data in response, GT200-PN-RS will write them to the address range of 0x0000-0x03FF. The specific data size will depend on users' configuration.
  • Page 15 The Master protocol works in Change of Value output mode and is executed as follows: 1. If command N is read, execute command N. Otherwise, check whether the memory mapping data contained in the request frame of command N is changed. If there is a change, execute the command N. 2.

Read a certain length of data from the buffer (input or output), byte swap processing, then put it in the frame buffer of the command, and finally send the command 2. When the command has a response, the data is separated from the response frame of the command ,byte swap processing, then copied to the buffer Note: When the byte swapping process is performed, the data to be processed is divided according to a specific length.

    GT200-PN-RS.Our "clear or hold" is for this mapped data area. Specifically, if "clear" is selected, all data in the map area will be set to 0 after the response timeout; if " hold", the content of the map data area will not be changed after the response timeout.

  • Page 24 “Check Mode”: There are three checking method: no parity check, CRC check, and sum check. Note that when the GT200-PN-RS transmits data to the PN side, the field will automatically lose the check value according to the check mode. For example, one byte of the end of the frame is discarded when the sum check is performed, and two bytes of the end of the frame are discarded when the CRC check is performed.
