![]() ![]() You have to use new ReadNoParameter WriteNoParameter-FB. The original FBs from the library ParameterRead and ParameterWrite work with this version of Refresh-FB, but some double word parameters of JX cannot be accessed.Some status bits are not read out of a JX/MX (Bit 4 = Zero speed,Bit 10 = Under voltage) the FB is much smaller than the original from the library, you will have much more space left for the main program.It is possible to choose the type of inverter with FB-parameter ModelTypJX,Ī bit has to be set for every inverter address, which is JX or MX, like in the scan list ![]() The version from March 2010 had several changes compared to the version from November 2009. If the communication is broken, Bit15 (error bit) is turned ON and all other status bits are turned OFF. The main difference is the improved error handling: It is smaller than the original, but can handle all Modbus node numbers from 1 to 31 (31 total on one PLC port). This version from July 2010 supports following inverters: There is an example CX-Programmer project attached. If you already know the Function Block from the library called _INV002_Refresh, you will find that only some status bits are missing and the set frequency has to be changed to be transmitted. CJ / CS1-PLC with SCU/SCB or CP1H / CP1L (except 10 point)Ĭable connections SCU (RS485 port) or CP1W-CIF11.To use MX2 and JX/MX inverter connected to a PLC with Modbus protocol a new version of the Function Block _INV002_Refresh.cxf (known from the CX-Programmer's library) is needed: INV_Refresh_X31_.cxf. ![]()
