4-1-3 Registration Table
Overview
A registration table is used to register Slave Units that are intended to participate at particular node
addresses (along with the models corresponding to the node addresses) to enable verifying that they
actually are participating. At the same time, using the registration table prevents unregistered Slave
Units and Slave Units of the wrong node addresses or models from participating in the network.
This function is enabled only in Registration Table Enable Mode, i.e., when pin 4 (REGS) is ON on the
Gateway Unit when the power is turned ON and the registration table data is normal. It can be used in
any communications mode.
If a Slave Unit is found to be not in agreement during the verification, the Registration Table Verification
Error Flag (status bit 01) will turn ON.
