Table 3-3. Maximum Number of DSM Modules per System by Baseplate and Power Supply Types
Power Supply Voltage:
Power Supply Current Draw by DSM:
5 VDC from PLC backplane
800 mA plus encoder supply current (see next item).
Available +5V Current/Module to supply
external encoder, if used:
500 mA (if used, must be added to module +5v current draw)
Model 350, 352, 360, 363, 364 PLCs:
(5 and 10-slot CPU baseplates,
5 and 10-slot expansion or remote
baseplates - 8 total baseplates per
system)
2 DSM314 modules in CPU baseplate with PWR321/322/328
5 DSM314 modules in CPU baseplate with PW330/331
3 DSM314 modules in expansion/remote baseplate with
PWR321/322/328
6 DSM314 modules in remote baseplate with PWR330/331
7 DSM314 modules in expansion baseplate with PWR330/331
20 total DSM314 modules per PLC system with PWR321/322/328*
20 total DSM314 modules per PLC system with PWR330/331*
*Note:
The Series 90-30 will normally support 20 DSM314 modules in a system. This number
may be reduced by other modules in the system, such as APM and GBC modules. It may also be
further reduced by having datagrams set up which will read the reference or fault tables. If the
configuration and user program is stored at the same time, the presence of either C blocks within
the LD program, or a C logic program may also affect the number of DSM314 modules which
may be included in a system. If the store fails, it may be possible to store the configuration to the
system by first storing the logic program, and then storing the configuration on a separate store
request.
The numbers listed in the above table are the theoretical maximums. However, an important
factor in determining the module mix in any baseplate is that the total power consumption of all
modules must not exceed the total load capacity of the power supply. It is possible that a
particular module mix would not allow the maximum number of DSM314s to be installed in a
baseplate due to power supply limitations. The VersaPro software’s configuration screen has an
automatic power supply usage calculator that can be used to check this. This calculation can also
be done manually, as explained in the
Series 90-30 PLC Installation Manual
(GFK-0356, version
P or later), which also lists load requirement specifications for Series 90-30 modules. The
