87 The I/O output points on the module are named from the next Y point, using the points on the host as endpoints. For example:
88
89 1. If the host is LX3V-1212MR-A and there are 12 output points (Y0 to Y7, Y10 to Y13).
90 1. If you expand an LX3V-16EY module on the host , the Y points defined in the module on the host computer are X20 to X27 and X30 to X37.
91 1. If you expand multiple I/O output point modules on the host, the I/Os on the module will be named in the same order.
92
93 (% class="box infomessage" %)
94 (((
95 **✎Note: **When adding IO expansion modules to the host, in principle, the number of all output points Y must not exceed 256 points. When adding IO expansion modules to the host, if the host needs to connect multiple IO modules, it is recommended to add a separate power supply board to the module for power supply.

102 As shown in the example above, it is LX3V-3624MT with two LX3V-16EY modules and one LX3V-4DA module. The host has 24 output points Y: Y0 to Y7, Y10 to Y17, Y20 to Y27. The output point in the module ① called by host are Y30 to Y37 and Y40 to Y47, and the output points in the module ③ called by host are Y50 to Y57 and Y60 to Y67.
