DL-PC/104
Bus Card Interfaces PCs to Allen-Bradley (AB) Networks
Highlights:
- Runs existing A-B (Allen Bradley) serial protocol at bus speeds
- A-B network speeds of up to 230.4 Kbaud
- Menu configuration; no jumpers to set
- Firmware in flash EPROM; reduces dependence on PC or disk
- 3-pin Phoenix screw terminal connector to A-B networks
- Ability to configure internally and externally - 5-pin Phoenix enables configuration using an external computer
- Card includes DH+ and RIO (Adapter) operation
The DataLink DL-PC/104 interface card provides PC/104 computers, MMIs, and OEM equipment with an inexpensive, high speed interface to Allen Bradley's Data Highway Plus or Remote I/O (Adapter).
The DL-PC/104 interfaces to a PC/104 CPU's bus using the same "Z182" COM port emulator as an internal modem. The DL buffers PC/104 bus data bytes in RAM memory, converts it to synchronous serial data, and then transmits to the A-B network at full speed.
The DL-PC/104's built-in CPU, RAM, and operating firmware in socketted flash Eprom frees-up computer memory and system resources for use by the application. The DataLink's unique serial port approach enables PC/104 bus computers to connect to A-B networks at high speeds using the same A-B DF1 serial drivers used with A-B PLC Channel 0, 1770-KF2 and 1785-KE etc.
The DL-PC/104 is designed for PC/104 applications running under operating systems including DOS, Windows 3.1, Windows 95, Windows NT, OS/2, Unix, QNX.
In Adapter mode the DL can be configured for 1 to 7 (virtual) racks. A computer can read all the I/O image tables in RIO, write 128 to 896 bits. The card can handle 16 block transfer reads and 16 block transfer writes per rack, for a total of 112 reads and writes of up to 64 words each.
Applications include:
- MMI, SCADA and OEM computer applications
- PLC Programming and Monitoring
- Data Transfer between PC and other DH+ nodes
- Off-line (self) tests
- On-line (DH+) diagnostics
