DL305 Specialty CPUs

The DL305 series offers four specialty CPUs for applications that require an unconventional PLC solution, such as computer-controlled I/O or execution of control programs written in BASIC instead of RLL.

The specialty CPUs are:

F3-OMUX-1 and F3-OMUX-2

The F3-OMUX (-1, -2) CPU plugs into the first slot of a DL305 base. It acts as a serial interface to the control program in the host computer and up to 184 DL305 I/O per CPU. Multiple CPUs can be daisy-chained together to increase I/O count. The host computer must use an OPTOMUX serial communication driver. The host can execute a custom program or use a standard software package that supports OPTOMUX drivers such as Intouch-Wonderware, Iconics-Genesis, U.S. Data FactoryLink, Metra-Skyhawk Lt, etc.

General Specifications:

• Two serial ports that support the OPTOMUX protocol
  F3-OMUX –1
  RS232C/RS422/RS485
  F3-OMUX-2
  RS422/RS485 (isolated)
  
  
• Max of 184 I/O points per CPU (with expansion base unit)
  
  
• Scan time is dependent on the communication speed, number of commands sent, type of commands sent, the size of the response and the speed of the host computer.

F3-PMUX-1

The F3-PMUX is similar in operation to the F3-OMUX (-1, -2). It uses a parallel interface instead of serial interface. As a result, it requires the host computer to use a PAMUX communication board (OPTO22 part number AC28 or equivalent). With this board, you can use PAMUX communication drivers in your host software. Scan time constraints are similar to the OMUX units.

F3-RTU-1

The F3-RTU-1 plugs into the CPU slot of the DL305 and directly controls a maximum of 184 I/O. This CPU executes programs written in interpreted FACTS extended BASIC (software included). Two serial communications ports support several protocols.

General Specifications:

• Two RS232C/RS422/RS485 selectable ports
  
  
• Port 1 can be controlled by BASIC.
  
  
• Port 2 is controlled by BASIC, MODBUS RTU (driver is downloaded into program space) or dedicated to DYNAMIC protocol. If the control program enables the Dynamic protocol, then this port will always respond to Dynamic requests independent of the Basic program operation (even if it is not running).
  
  
• Control up to 184 I/O points per CPU.
  
  
• Scan time is dependent on the BASIC program. Automatic I/O update every 10ms(user-adjustable in 10ms increments)
  
  
• Built-in Real-Time Calendar Clock
  
  
• Floating-point math for complex calculations
  
  
• 128K battery-backed RAM
  
  
• Special instructions simplify on/off control
  
  
• Extensive string handling statements for string manipulation of communications with serial devices.
  
  
• Special features for unsolicited report by exception, time stamping, program up/download over SCADA network.
