Program Storage Device



The 1747-PSD Program Storage Device is a hand-held program transfer device. With this device, you can store and retrieve a single program for MicroLogix 1500 processors. Use a 1761-CBL-PM02 cable to connect the device to the RS-232 port running DF1 full-duplex communication protocol.

Data Access Tool

The 1764-DAT MicroLogix 1500 Data Access plug-in tool provides an interface for on-the-fly data monitoring and adjustments.

Features include:

• Direct access to 48 bit elements
  
• Direct access to 48 integer elements
  
• Two function keys
  
• Display of controller faults
  
• Removal and insertion under power
  

Real-Time Clock and Memory Modules

These optional modules attach to the processor unit. Both types of modules can be inserted or removed while the unit is under power.

1764 Real-Time Clock Modules

• Establish a time-base for controller functions that need to be coordinated with real-time events.
  
• Provide year, month, day of month, day of week, hour, minute, and second information to the controller by using the RTC function file.
  

1764 Memory Modules

• Allow user programs and data to be stored as backup.
  
• Transport programs for use with other controllers.
  
• Allow safety/security for press control and other critical applications.
  
• Enable auto-recovery, through a power cycle, after a controller fault.
  
• Allow comparison of programs.
  
• Enable data file and memory module write protection.
