Chapter
Installing the BASIC Module 1
1 -10
You install the BASIC module in a 1771-I/O chassis. You can place your
module in any slot of the I/O chassis except for the extreme left slot
(his slot is reserved for processors or adapter modules). We recommend
that you remember these points:
When selecting slots for modules, always try to group modules to
minimize adverse effects from electrical noise and radiated heat.
Group analog and low-voltage dc modules away from ac modules or
high-voltage dc modules to minimize electrical noise interference.
Important: Certain processors restrict the placement of block-transfer
output modules. Refer to the user manual for your particular processor for
more information.
Refer to this table to determine where the BASIC module fits into your
module group and address scheme. For more information on jumper JW5,
see Set Backplane Configuration on page 1 -7.
If using this chassis addressing: If JW5 is set to 8-pt. mode: If JW5 is set to 16-pt. mode:
2-slot place the BASIC module in any
module group with any 8-bit discrete
or block transfer module not permitted
1-slot place the BASIC module in any
module group with any 8-bit, 16-bit,
discrete or block transfer module place the BASIC module in any
module group with any 8-bit, 16-bit
discrete or block transfer module
1/2-slot no restrictions no restrictions
