9 ANYBUS COMMUNICATION
The ECW500 supports multiple network protocols with the use of passive and active Anybus modules.
When using a passive module, the settings applied are the same as the Modbus RS-485 / RS-422 (parameters
30002 to 30014).
For active modules, you may need to adjust the network settings (parameters 31124 to 31148 and 31204) as
well as Modbus settings (31198 to 31202). The mapped parameters must be defined in parameters 31150 to
31172 (read) and 31174 to 31196 (write). It is necessary that at least one read parameter and one write
parameter be configured for the correct operation of the cyclic communication. The first parameter not
configured (value 39998 for reading and 30000 for writing) disables the use of the other parameters in the
sequence.
You can monitor the system status from the status word (parameter 31214) and also apply commands through
the command word (parameter 31216). See below for a detailed description of these parameters.
<
31214 >
Status word
It allows monitoring the equipment status. Each bit represents one state:
Bits Values
Bit 0
Regulator Status
0: Regulator OFF
1: Regulator ON
Bit 1
Ramp State
0: Startup ramp disabled
1: Startup ramp acting
Bit 2
LUF
0: LUF disable
1: LUF acting
Bit 3
LEOC
0: LEOC disable
1: LEOC acting
Bit 4
LEUC
0: LEUC disable
1: LEUC acting
Bit 5
LTOC
0: LTOC disable
1: LTOC acting
Bit 6
Mode Transition
0: Ramp of transition mode disabled
1: Ramp of transition mode acting
Bits 7 to 31 Reserved
<31216> Command word
It allows the control of the equipment via the network. Each bit represents one command and the signal must
be pulsed, sending high logic level to execute the command:
Bits Action
Bit 0 Regulator ON
Bit 1 Regulator OFF
Bit 2 Automatic mode
Bit 3 Manual mode
Bit 4 Enable online
Bit 5 Disable online
Bit 6 Parallel Enable
Bit 7 Parallel Disable
Bit 8 Reset alarms
Bit 9 Reserved
Bit 10 Reserved
Bit 11 Reserved
Bit 12 Reserved
Bit 13 Reserved
Bit 14 Perform auto tuning (autotuning)
Bits 15 to 31 Reserved
