10. Assigning the Remote Input and Output Addresses etting Started Assign the Addresses Remote I O Data Types If you ve used a DL205 CPU and I O before then you probably know that the CPU will automatically assign the local input and output addresses That is the CPU automatically assigns input points starting at XO and output points starting at YO In a remote I O system your program must assign the starting addresses and ranges to the remote input and output points To make the address and range assignments requires setup logic in your control program The D2 RMSM has specific memory locations called shared memory that tell it how to assign the remote I O addresses First you must use the tables in Appendix B to look up the next available starting address for the data type you want to use Then you must calculate the number range of input and output points used per slave You use acombination of LDA LD OUT and WT instructions to store this information in the shared memory There are additional setup parameters which the setup program must write to the shared memory of the D2 RMSM these are discussed in detail in Chapter 4 In a local system the CPU assigns input addresses starting at XO and output addresses starting at YO In aremote I O system you can choose this conventional method or you can choose to assign the inputs and outputs to other data types For example you could assign the remote inputs and outputs as the
