Apex Digital 5708009-C manual AE Profibus Protocol, Host port connector with Profibus

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).
