HanYoung GR100 communication driver

HanYoung GR100 Modbus communication driver is the driver to communicate with graphic recorder controller of HanYoungNux  Co,. Ltd. in Korea.

Note) HanYoung GR100 Modbus communication driver basically use Modbus protocol.

1. Read settings

<Figure 1> is read setting example of HanYoung GR100 Modbus communication driver. 

<Figure 1>  Read setting example of HanYoung GR100 Modbus communication driver

Device part of  <Figure 1> input Com Port(COM1), Baud Rate(19200), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively according to setting of controller.

In protocol option part, you can set the following: whether to check CRC(1 = check, 0 = No check, default : 1), bit write value that corresponds to ON(Default = 1), use of HanYoung GR100 IP protocol(1 = use, 0 = serial, default : 0), bit write value that corresponds to OFF(Default = 0), whether to use WORD size when DWORD/FLOAT reading(1 = Not using WORD size, 0 = using WORD size, Default = 0). Each argument have to separate by comma( , ).

Note) HanYoung GR100 IP protocol is used in systems that are connected by Ethernet(TCP/IP or UDP/IP).
