Caractéristiques Avantages

• Create BASIC programs to transfer data between the ControlLogix and the MVI56-BAS module.
• Create foreign device interface for specific applications and easily integrate the device with the ControlLogix processor.
• Interface to many devices that use ASCII interface to a ControlLogix backplane such as modems, printers, bar code readers, and scales.
• Save ControlLogix processor memory by running math algorithms.
• The module acts as DF1 full-duplex device or a DF1 half-duplex slave.

Spécifications

General Specifications

• Single Slot - 1756 backplane compatible
• The module is recognized as an Input/Output module and has access to processor memory for data transfer between processor and module.
• Ladder Logic is used for data transfer between module and processor. Sample ladder file included.
• Configuration data obtained from configuration text file downloaded to module. Sample configuration file included
• Local or remote rack

Functional Specifications

The BASIC programs are stored in the MVI56-BAS Compact Flash disk
allowing the user to easily backup the BASIC programs to another Compact
Flash disk or to a local PC. Up to 24065 Bytes of RAM are available.

The module contains three ports:

• DH-485: DH-485 communication or BASIC program transfer
• PRT1: ASCII communication or program port
• PRT2: ASCII communication or DF1 communication

The user can either create the BASIC programs using the command line, then
save it to Compact Flash, or create the program on a PC and download it to the
MVI56-BAS module. The user can also configure the module to execute a
BASIC program automatically at power up.

• Supports BASIC-52 Programming language
• Stores BASIC programs on Compact Flash disk
• Supports 24064 bytes of RAM
• Easy BASIC program backup

DF1 Communications

• PRT2 can be enabled and configured for DF1 Communications through BASIC calls
• Uses ladder logic to transfer data between the DF1 device and the ControlLogix processor
• PRT2 port can be configured to act as a full-duplex device or half-duplex slave

The MVI56-BAS can send the following DF1 commands:

• PLC-2 unprotected READ command
• PLC-2 unprotected WRITE command
• PLC-3 word range READ command
• PLC-3 word range WRITE command
• PLC-5 typed READ command
• PLC-5 typed WRITE command

The MVI56-BAS accepts the following commands:

• PLC (word range writes)
• PLC (typed writes)
• PLC (unprotected write)
• SLC 5/02 (unprotected write)
• SLC 5/02 (typed writes)

DH-485 Communications

• The MVI56-BAS DH-485 port can be used to interface the ControlLogix processor with DH-485 Devices
• Rockwell Automation AIC+ device is required (user-supplied)
• Ladder logic is required to transfer data between the ControlLogix processor and remote data file or common interface file
