WARNING If your communications cable is not wired exactly as shown in our cable
assembly instructions, damage to the HMI or loss of communications can
result.
The PLC station number cannot be the same as the HMI station number.
Summary
Maple Systems Graphic HMIs communicate with Siemens S7-200 SMART modules via PPI.
When configured with EZware, the Graphic HMI is the master in a point-to-point single
master, single slave format. Please refer to the Installation and Operations Manual for
information on connecting multiple Graphic HMIs to a single PLC port.
Communications
The Graphic HMI should be connected to the controller’s PPI port. A list of communications
cables offered by Maple Systems as well as cable assembly instructions to assist you in
assembling your own communications cable are available on our website at
www.maplesystems.com.

Register Memory
The following table lists the PLC’s register memory ranges that the Graphic HMIs are able to
access. Please note that your PLC’s memory range may be smaller or larger than that
supported by these HMIs. The following register memory can be displayed in 16-bit or 32-bit
format on the Maple HMI.
(Note: d=decimal )
Discrete Memory
The following table lists the PLC’s discrete memory ranges that the Graphic HMIs are able to
access. Please note that your PLC’s memory range may be smaller or larger than that
supported by these HMIs. The following discrete memory is displayable in single-bit format
on the Maple HMI.
(Note: d=decimal, o=octal)
