SOME BODY KNOW WHY I CAN ONLY READ INPUT STATUS OR COIL STATUS FUNCTION 01 AND 02 WITH A CP341 RS485 MODBUS SLAVE? I HAVE A CP341 RS485 MODBUS SLAVE AND IAM USING MODSCAN32 SOFTWARE IN MY PG LIKE A MASTER, BUT WHEN I TRY TO READ AN HOLFING REGISTER OR INPUT REGISTER IS NOT POSSIBLE, I CAN READ COIL AND INUTS BUR REGISTERS NOT IS POSSIBLE. IF I MONITORING THE BLOCK FB80 APPEAR ERROR W#16#005C AND THE ERROR INFO W#16#1E0F, I LOOKING FOR THESE ERRORS IN MANUAL BUT ONLY SAID Error when executing a RECEIVE/FETCH call with FB7 (RCV_RK) AND SAID TO RESOLVE THE ERROR: Analyze FB7-STATUS I DONT KNOW WHAT ARE HAPPENING. TO FUNCTION 03 06 AND 16 IAM USING A DB8 AND TO FUNCTION 04 I USE DB9. FOR THESE DB`s I HAVE TO DECLARATE SOME SPECIAL VARIABLES OR ONLY I DECLARE THE WORD I WILLUSE (FOR EXAMPLE REGISTER 40001 - DB9.DBW0. REGISTER 40002-DB9.DBW1, AND SO ON).
