RS485 Modbus-RTU communication parameters:
Command Reply Description
CMAn CMA;&| Sets the Modbus-RTU address (1…247) to n. Default=1
RMA RMA;n| Reads the Modbus-RTU address.
CMBn CMB;&| Sets the Baud Rate:
9600 if n=0
19200 if n=1 (default)
38400 if n=2
57600 if n=3
115200 if n=4
RMB RMB;n| Reads Baud Rate setting.
CMPn CMP;&| Sets parity and stop bits (data bits = 8 fixed):
8N1 if n=0
▪
8N2 se n=1
8E1 if n=2 (default)
▪
8E2 se n=3
8O1 if n=4
▪
8O2 se n=5
RMP RMP;n| Reads the setting of parity and stop bits.
CMWn CMW;&| Sets waiting time after transmission with Modbus-RTU
protocol:
Immediate reception if n=0 (violates protocol)
Waiting 3.5 characters if n=1 (respects protocol)
Default : Waiting 3.5 characters (n=1)
RMW RMW;n| Reads the setting of waiting time after transmission with
Modbus-RTU protocol.
Analog output (only LPS10MA…):
Command Reply Description
CASn CAS;&| Sets the analog output type:
0…20 mA if n=0
4…20 mA if n=1 (default)
0...1 V if n=2
0...5 V if n=3
0...10 V if n=4
RAS RAS;n| Reads the type of analog output set.
CAInnnn CAI;&| Sets nnnn as irradiance minimum value in W/m
2
for the
analog output. Min=-200, default=0
RAI RAI;nnnn| Reads the irradiance minimum value in W/m
2
for the
analog output.
CAFnnnn CAF;&| Sets nnnn as irradiance maximum value in W/m
2
for the
analog output. Max=4000, default=2000
RAF RAF;nnnn| Reads the irradiance maximum value in W/m
2
for the an-
alog output.
CAin CAi;&| Sets the direct or reversed correspondence between ana-
log output and irradiance:
If n=0: Min. output Min. irradiance
Max. output Max. irradiance
If n=1: Min. output Max. irradiance
Max. output Min. irradiance
Default : Direct correspondence (n=0)
RAi RAi;n| Reads the type of correspondence (direct or reversed)
between analog output and irradiance.
