-====== MODPORT Expansion ======
-To expand the I/O capabilities and features (analog input/output, temperature input, etc…), [[https://comfiletech.com/field-i-o/modport-i-o-module/|MODPORT]] modules can be added.
-{{ :msb_modport_expansion:modport.png?nolink |}}
-What is the MODPORT? It is a modular Modbus field I/O controller with features that
-include digital I/O, analog I/O, temperature input, and a variety of others.
-The MSB764T can be connected to the MODPORT's 5-slot board as shown in the figure
-above. The MODPORT header module is not needed.
-The MODPORT can be controlled using a set of dedicated commands listed below. The MODPORT can
-only be controlled using BASIC; Ladder Logic control is not supported.
-  * [[cubloc:mpadin:index|MPADIn]] - Reads from the MD-ADIN4 analog to digital input module.
-  * [[cubloc:Mpdaouta:index|MPDAOutA]] - Writes to the MD-DAOUT2B digital to analog current output module.
-  * [[cubloc:Mpdaoutv:index|MDDAOutV]] - Writes to the MD-DAOUT2 digital to analog voltage output module.
-  * [[cubloc:Mphadin:index|MPHADIn]] - Reads from the MD-HADIN4 high resolution analog to digital input module.
-  * [[cubloc:Mpin:index|MPIn]] - Reads from the MD-DIDC8 digital input module.
-  * [[cubloc:Mprelay:index|MPRelay]] - Writes to the MD-DORL8 digital output relay module.
-  * [[cubloc:Mpsink:index|MPSink]] - Writes to the MD-DOSI8 digital output sink module.
-  * [[cubloc:Mpsource:index|MPSource]] - Writes to the MD-DOSO8 digital output source module.
-  * [[cubloc:Mpthin:index|MPThIn]] - Reads from the MD-THRT4 temperature input module.
-For instructions on how
-to wire the MODPORT's inputs and outputs, please see the [[https://comfiletech.com/field-i-o/modport-i-o-module/|MODPORT manual]].
-By daisy-chaining as many as four 5-slot boards together, the system can be
-expanded to maximum of 20 MODPORT modules.
