hey, i guess you know the chapter 3.9.2. of the manual. You have checked that the PAC 3200 is in modbus tcp mode and you are using in your S7-400 the right modbus function codes 0x03 and 0x04 (for H systems i guess you almost only use 0x03 and 0x04)? Which CPU and which CP do you use with modbus tcp? Best regards, Fafner |

igg... You can use PAC 4200 in your future projects for MultiMaster communication. * I guess it supports 3x masters/ polling data from 3x places at a time. |
