ERZ 9000 T Corrector use MODBUS protocol. So you have to use 'DLL-MOSBUS2' communication driver.
ERZ 9000 T is the Corrector controller of Karl Wieser Gmbh in Germany.
Note) Help of DLL-MODBUS2 communication driver
<Figure 1> is read setting example for ERZ 9000 T Corrector controller.

Device part of <Figure 1> input Com Port(COM1), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to setting of controller.
Also you can input 'check enable/disable of CRC' (1 : enable, 0 : disable, default = 1) by using option part.
ERZ 9000 T Corrector controller¡¯s read schedule
Read schedule setting parameters are as follows:
1) Station – Controller station number(modbus address) = 1 ~ 247.
2) Read Command – Command = 3, 3D, 3d, 3M, 3m, 3F, 3F2, 3f, 3f2, 3b, 3W.... ( Refer to <Table 1> )
3 – Read of Word unit modbus data,
3D – Read of Dword unit modbus data, ( data order = LO, HI )
3d – Read of Dword unit modbus data, ( data order = HII, LO )
3M – Read of HI Word x 10000 + LO Word double word unit modbus data, ( data order = LO, HI )
3m – Read of HI Word x 10000 + LO Word double word unit modbus data, ( data order = HI, LO )
3F – Read of Float unit modbus data, ( data order = LO, HI )
3F2 – Read of Float unit modbus data, ( data order = LO, HI type 2)
3f – Read of Float unit modbus data, ( data order = HI, LO )
3f2 – Read of Float unit modbus data, ( data order = HI, LO type 2 )
3B – Read of Byte unit modbus data,
3W – Read of Word unit modbus data ( data order = LO byte , HI byte )
3) Read Start Address – Read start address. ( address = modbus address - 1)
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – Read size.
3, 3W – Word unit size,
3D, 3d, 3M, 3m, 3F, 3F2, 3f, 3f2 – 2 Word unit size,
3B – Byte unit size.

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.
You can write the setting value by using write settings.
Digital Write
Digital write and analog write have the same setting parameters except output value.
Analog Write
Analog write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Controller station number(modbus address) = 1 ~ 247.
3) ADDRESS Write address of deciminal unit. ( address = modbus address - 1)
4) Extra1 Write command.
