Drive Network Connectors
TTL-level. Uses standard RJ-45 style 8-pin modular connectors. Any
standard category-5 Ethernet cable (found in most electronics stores) 5 meters
or less in length can be used to connect the PBDP-110 to the drives.
MMI Port Connector
RS232-level. Use the DB9-to-RJ-45 cable supplied with the PBDP-110 kit to
interface with the unit via the Flashloader programming utility (refer to section
12).
Input/Output Data
The PBDP-110 presents a modular interface, supporting four different modules
depending on the number of drives connected to the unit and the desired data
sizes.
If the PBDP-110 is configured for one drive (the Channel A drive) with standard
data access, the interface’s cyclic data sizes are fixed at 16 bytes of output
(control) data configured as four 32-bit words, and 24 bytes of input (status)
data configured as six 32-bit words.
If the PBDP-110 is configured for both drives (Channels A and B) with
standard data access, the interface’s cyclic data sizes are fixed at 32 bytes of
output (control) data configured as eight 32-bit words, and 48 bytes of input
(status) data configured as twelve 32-bit words.
If the PBDP-110 is configured for one drive (the Channel A drive) with compact
data access, the interface’s cyclic data sizes are fixed at 4 bytes of output
(control) data configured as two 16-bit words, and 8 bytes of input (status) data
configured as four 16-bit words.
If the PBDP-110 is configured for both drives (Channels A and B) with compact
data access, the interface’s cyclic data sizes are fixed at 8 bytes of output
(control) data configured as four 16-bit words, and 16 bytes of input (status)
data configured as eight 16-bit words.
Via these data structures, any data item (commands, monitor data and
parameters) available in the drive can be accessed. For detailed explanations
of the format and usage of this data, refer to sections 9 and 10 of this
document.
Versatile 3-Way DIN-Rail Mounting System
The unit’s enclosure is provided with a mounting clip attached to the rear of the
unit. This clip allows the unit to be mounted 3 different ways:
• For DIN rail mounting, snap the mounting clip onto a standard DIN rail,
and then snap the unit enclosure onto the clip’s retaining tabs. This
allows easy removal or repositioning of the unit on the DIN rail during
wiring.
• For panel mounting, the mounting clip can be bolted directly to a flat panel
via the two bolt holes at the top and bottom of the clip. Refer to section
