Apex Digital 5708009-C manual Devicenet Rotary Switches Baud Rate and Addressing

Advanced Energy®

Analog outputs automatically set the output voltages to 0 V if too much time elapses after the last Poll Command message received by the device. At this timeout condition, the output of the generator shuts off and goes safe.

DEVICENET ROTARY SWITCHES: BAUD RATE AND ADDRESSING

The DeviceNet interface features three rotary switches, located on the rear, which are read each time the DeviceNet interface powers up. Use the Data Rate switch to select a baud rate: 125, 250, or 500 kbaud (0 = 125;1 = 250; 2 = 500 kbaud). The default is 500 kbaud. A switch setting in the PGM region lets you configure the baud rate through DeviceNet.

The signals available at the RS-232, AE Bus Host port conform to the RS-232 interface standards. Each generator is factory preset for a baud rate of 19.2 kb and Address 1. Table 4-4 describes the RS-232, AE Bus Host pin signals.

Use the MSD and LSD switches to select the unit’s address (MAC ID). MAC IDs 0 through 63 are valid. Use the MSD switch to select the MAC ID’s most significant digit; use the LSD switch to select the MAC ID’s least significant digit. Switch settings greater than 63 (or in the “PGM” region of the MSD switch) let you configure the MAC ID through DeviceNet.

DEVICENET CONTROL PANEL LEDS

The rear panel of the Apex generator features two, bi-color LEDs (see Figure 4-20). One is labeled MOD and indicates module status. The other is labeled NET and indicates network status.

Devicenet Module Status LED

The MOD bi-color (amber/green) LED provides device status. It indicates whether the device has power and is operating properly. Table 4-14 shows the LED’s various states and meanings
