2 INTRODUCTION TO PLC300
PLC300 is a PLC with integrated HMI, developed to meet the need of interface with the
user on panels and machines and at the same time a complete expandable PLC, fast
and with several communication ports, enabling the product to be master of CANopen
networks (CAN network) and/or Modbus RTU (RS-485 network) as well as Modbus TCP
(Ethernet network).
Some important characteristics:
High processing speed:
The PLC300 uses a 32 bit ARM Cortex-M3 processor, running at 120 MHz, which provides
a high processing speed.
HMI - Human-Machine Interface:
The PLC300 has an integrated HMI with LCD display with backlight of 4 lines and 20
characters each, in addition to the keyboard with function keys programmed by the user,
all with LEDs, <ALARM> key, <HOME> key, etc., and alpha-numeric keyboard.
Version without HMI:
It is possible to assemble the PLC on a DIN rail, in a version without HMI (keyboard and
display). In this case, the back part of the product becomes the front and features a small
display of 2 lines and 16 characters with a button to check the I/O status.
Programming:
In addition to the ladder programming, the WPS allows the assembly of the screens,
graphically, configuration of the alarms, assignment of the function keys, configuration of
the equipment, besides the firmware, which can be updated directly via PC.
The programming can be done via USB, Ethernet or Serial RS232 and RS485.
Hot Download:
Allows hot loading of the resource, that is, it is possible to change the ladder program,
screens, alarms and logs with the current program running, and after the conclusion of
the download, the new program is executed automatically. For further information, refer
to the WPS manual.
Large memory capacity:
The PLC300 features a static RAM memory with battery and capacity of 1 MByte to store
screens, alarms, program and other user’s data. The memory allocation can be configured
by the user via the WPS.
Bootloader:
The bootloader is an auxiliary program that executes the main firmware of the PLC300,
which, in turn, executes all the functionalities.
It is through the bootloader that new firmware can be saved to the PLC300 via USB or Serial.
