Device Features
VersaCloud M2M Connectivity is utilized in the ladder diagram program by the VCLOUD Function block. This block is added to the
ladder diagram as needed and includes a Properties window when it is placed that determines the Send and Receive variables
(data). See Figure 2-41.
For details regarding VersaCloud M2M Portals, the VCLOUD Function block and using VersaCloud M2M connectivity, refer
to the P-Series EZ LADDER Toolkit Manual. It contains more details on configuring and using VersaCloud and in-depth
information for advanced configurations and usage.
Ladder diagram and Structured Text examples for using VersaCloud, GPS, Cellular Data and more are available for

Battery Backed up S-RAM Memory
The VersaGateway supports 4, 1 Mbit Static RAM (512K) integrated circuits (S-RAM ICs). These four individual chips hold data on
power loss as they alternately powered by the on-board lithium battery. This RAM is suited for data-buffering for communications
like VersaCloud M2M Connectivity.
To use this S-RAM, custom structured text functions and function blocks will have to be written to store and retrieve data.
Each chip is an SPI device and may be accessed via Structure Text only using target specific functions like the EZ_SpiWrite
Data. Please see the SPI data listed to access each chip. For more detailed information how to use Structured Text, refer to
the P-Series EZ LADDER Toolkit Manual.
When the VersaGateway is selected from the Project Settings, the SPI Port 1 (SPI1) and the Chip Select (CS) General Pur
pose I/O (GPIO) is automatically installed and reserved in the target settings. No Project Settings configurations are
needed.
