You
can either use the built-in Analog Digtal Converter to connect to temperature sensors that
can output 0-5V or 4-20mA, or using external temperature module that are equipped with
communication capability to measure temperature.

| Thermistors can be
used to measure temperature in many different environments. They are both rugged as well
as low cost but are non-linear device. This application note explains how to
physically connect a 10K Precon thermistor to the PLC using the PLCs on board ADC as well
as how to use a look up table and interpolation method to calculate accurate temperature
readings from the non-linear thermistor inputs. Click to Download

| Thermocouple are
widely used in industry but their very low signal output (micro volts) would require
amplification to get 0-5V for the PLC ADC input. Alternatively, you can purchase an
IPC-DAS I-7018 module that has 8 built-in
thermocouple ports. The following application shows how to communicate with I-70xx module
via RS485 port. Click to Download Application Note |

Each
application note explains how to use an M-Series PLC to control another PLC or multiple
PLCs in a remote I/O network. In each situation one M-Series PLC would be the master and
either E10+ PLC/s or M-Series PLC/s would be the slaves and serve as remote I/O to the
master. Each application note comes with a sample program.

Using E10+ PLCs as Remote I/O - Basic |
| This
application note explains how to use an M-Series PLC to control the E10+ PLC. The
programming is fairly simple, allowing only a few E10+ PLCs to be controlled in the
network. Click to Download Application Note
|
| 2) Using
E10+ PLCs as Remote I/O - Advanced |
| This application
note explains how to use an M-Series PLC to control the E10+ PLC. The programming is a bit
more advanced but up to 255 E10+ PLCs can be used as remote I/O. Click to

| 3) Using
Super PLCs as Remote I/O - Basic |
| This application
note explains how to use an M-Series PLC to control other Super PLCs using the Modbus
protocol. The programming is fairly simple, allowing only a few Super PLCs to be
controlled in the network. Click to Download Application Note
|
| 4) Using
Super PLCs as Remote I/O - Advanced |
| This application
note explains how to use any TRi Super PLC (Nano-10, FMD, F-series or M-series PLCs) as
remote I/Os for a master TRi Super PLCs. The programming is more advanced and more than
250 TRi Super PLCs can be used as remote I/O. Click to

Saveral
sample programs in VB6, VB Express and GNU C++ are provided in this app notes to assist
users to write program that run on a PC/Mac to communicate with the PLC via the serial
port or the Ethernet port.

| A User can easily
program his/her PC to connect to a Super PLC via TCP/IP (Ethernet or Internet) and
send/receive ASCII based host link commands. The sample project as well as a DLL provided
below is a good starting point to learn how to do so. Download VB

The
project contributor (Albert Martinez)
needed a solution to fill an Excel preadsheet with DM data over multiple rows, with each
record being inserted into a new row. This functionality is achieved with a simple VBA
macro function.
