Apex 1 to 5.5 kW Generator
AE PROFIBUS PROTOCOL
Profibus (Process Field Bus) is an interface that lets you communicate with your Apex
generator from a host (master). AE manufactures a certified Profibus, which means
the interface is tested and certified to work with Profibus masters described in the DIN
19245 Profibus Standard DP, part III. Any Profibus master that complies with this
standard can communicate with AE’s certified Profibus.
Note: Before controlling/monitoring the Apex generator through the host port, you
need to ensure that the required User port inputs are satisfied and that the
control mode is properly set. The required User port inputs are identified under
the Satisfying Minimal Requirements section for your User port. To determine
which User port you have, see the PIN position 8 in Table 1-1. on page 1-4. The
control mode is usually set to the PROFIBUS as default when this host port
option is installed. To ensure the control mode is set to host, see commands 14
(sets control mode) and 155 (reads control mode) in the “Profibus Command
Set” on page 4-66.
The Profibus Host port on the generator is a 9-pin, female, subminiature-D connector
and an eight-switch DIP located beneath the connector, which is used to set the Apex
generator’s network address (see “Setting the Network Address with the Profibus DIP
Switch” on page 4-60).

Note: AE’s Profibus protocol does not support the following functions: address
changing, freeze/unfreeze modes, or sync modes.
