Transducer P30

The  PC  card  transmission  line  marking  depends  on  the  card
manufacturer.

5. .2. MODBUS protocol description

The implemented protocol complies with Modicon’s PI-MBUS-

300 Rev G specification. P30U MODBUS protocol serial interface para-
meters :

Transducer address 1..247.
Transmission rate: 4800, 9600, 19200, 38400, 57600, 115200,
230400, 256000 [b/s].
Operation mode: RTU with the frame format: 8n2, 8e1, 8o1, 8n1.
Maximum time to start response: 200 ms (the response time may
get longer up to 500ms during saving the data to the SD/SDHC
card).

Serial interface configuration consists of setting the transmis-

sion rate, device address and the information unit format – protocol.
