Productivity Open P1AM Industrial Arduino P1000 Expansion Digital Inputs and Outputs Part 2


In part 1 we adding additional discrete input and output modules (cards) to our P1AM-START1 ProductivityOpen starter kit with Ethernet. A program was then discussed that will print the modules in our system and then set and reset discrete digital inputs and outputs.
P1-16TR – Productivity1000 relay output module, 16-point, 6-24 VDC/6-120 VAC, (16) Form A (SPST) no-suppression, 2 isolated common(s), 8 point(s) per common, 2A/point, 8A/common.
P1-16CDR – Productivity1000 discrete combo module, Input: 8-point, 24 VAC/VDC, sinking/sourcing, Output: 8-point, 6-24 VDC/6-120 VAC, relay, (8) Form A (SPST) relays, 1A/point.
P1-08SIM – Productivity1000 simulator input module, 8-point.


We will now discuss additional instructions in our industrial Arduino controller that will be used with our P1000 expansion modules. (cards) Our sample sketch will include a simple start/stop circuit and a shifting circuit.
Let’s get started. Continue Reading!

Productivity 1000 Series PLC Modbus ASCII Protocol

Modbus is a communication method used for transmitting information over serial lines between electronic devices. The device requesting the information is called the Modbus Master (Client) and the devices supplying information are Modbus Slaves (Servers). This protocol was originally developed by Modicon systems.
Modbus protocol comes in basically three different types. Ethernet (Modbus TCP) or Serial (Modbus RTU or Modbus ASCII). Modbus TCP and Modbus RTU come as standard protocols in the productivity series of PLCs.

We will connect the Productivity 1000 PLC to a Solo process temperature controller. This will be done using the Modbus ASCII protocol over serial RS485 communication wire. (Media) The present and set values (PV / SV) will be read from the Solo controller and the set value will be written when required. Let’s get started. Keep on Reading!

Productivity Open P1AM Industrial Arduino P1000 Expansion Digital Inputs and Outputs Part 1


The productivity open P1AM I/O interface chip-set supports the full suite of Productivity 1000 I/O expansion modules. These modules are industry approved and proven in the industrial environment. Modern industrial signal levels for digital and analog inputs and outputs are used.

P1000 modules available to you include the following:
• Discrete
• Analog
• Temperature
• Relay
• High-speed Input
• PWM

We will be adding additional discrete input and output modules (cards) to our P1AM-START1 ProductivityOpen starter kit with Ethernet. A program will then be discussed that will print the modules in our system and then set and reset discrete digital inputs and outputs.
