SODIMM

from Siemens

Powerful, tiny and easy-to-use these are the attributes of profichip’s
SODIMM-PLC module. Equipped with a rich set of direct IO and
communication features, programmable in Step7 from Siemens and
up to 512kB of PLC user memory this module is the ideal extension to various types of applications where fast, deterministic and reliable hardware PLC control in a small form factor is required. Board
Controllers, HMIs and a broad range of machinery can benefit from new
control capabilities and direct IO- and communication functions. Supporting a very popular programming language, a well-known tool chain
and extensive maintenance features will further increase the market acceptance and success of the final product.

The SODIMM-PLC module is build around profichip’s PLC 7001 chip.
Based on the core of the PLC 7000 which has been in use for almost
four years in over 10.000 applications worldwide, the PLC 7001 offers
extended IO features with up to 32 digital inputs and 24 digital outputs
directly on-chip. The IO interface is configurable to provide high level
user functions like numerous hardware counter modes.
16 digital inputs can be employed with on-chip alarm functionality which
results in low latency and fast response times upon critical system conditions and provides the capability to capture time critical events very
accurately. The build-in Real-Time-Clock which can be buffered by an
external battery allows precise timestamping and clock synchronized
control tasks. SSI interface for rotary encoders, 4-channel Pulse-WidthModulation and Stepper-Motor-Control are to be supported in future
firmware updates.
If more than 56 digital I/O bits or analog functions are needed a
serial I/O bus is provided which can be operated with up to 32
peripheral modules compatible with System 200V from VIPA.

Alarms (e.g. OB 40)

User Data Interface
For maximum flexibility and convenient adaption the SODIMM-PLC module is equipped with a 16 bit SRAM interface to an external FPGA or
Dual-Port-RAM with up to 1024 bytes address space mapped into the
PLC I/O area. This interface can be used to easily share data of external communication interfaces like PROFIBUS- or CAN-Master with the
integrated PLC memory as well.

Communication Interfaces
Currently there are three serial interfaces and one Ethernet port
available on the SODIMM-PLC module. The serial interfaces are
dedicated to MPI communication, PROFIBUS-DP Slave interface
(both supporting transmission rates up to 12 MBit/s) and a serial standard interface (e.g. for establishing a Point-To-Point (PtP)
communication). The Ethernet port is restricted to PU/OP functionality like hardware configuration, PLC program download and online functions. Alternatively the MPI interface can be used for system
setup, program update, debugging and online functions.
