Hi guys: I had been using all type of PLC, from Festo to AB. Omron seems to be getting better & better from the OLD Syswin to the CXP. I always got the headache comparing data. Especially the BCD. In order to get rid of the message below: "WARNING: Symbol Sartorius's data type (UDINT_BCD) is not compatible with the data type (UINT) for this instruction operand at rung 10 ( 0, 0 ). " I always need to convert it back to hex and then performed the comparison instruction. Any body have any suggestion. Or I just continue to used the conversion method or plainly ignored the messages and continue to compare with the "Hex" comparison instruction. Thanks Simon
