The DIP switches on the Allen-Bradley FM131 base have been messed up – what should I do?
Thread Content
The module connected to the FM131 base is the FM143E, but the positions of the DIP switches on the base have been manually altered. Is there any way to restore them?
Binary: Check the instructions and calculate it yourself to adjust it back
That dial is used to set the address. What’s your address?
The 8-digit DIP switches on the base are set according to the binary values of the predetermined module communication addresses. When a particular position of the DIP switch is in the ON position, the corresponding binary value is 0; when it is in the OFF position, the value is 1. The lower bits of the DIP switches correspond to the lower bits of the module address’s binary value. The 8th bit is effective when redundancy is used. The correspondence between the binary bits of the module communication address and the positions of the DIP switches is shown in Figure 4-1. In this figure, the module communication addresses corresponding to the various DIP switch positions are 120 or 0x78
