PCD7.L310 Analogue module with 4 inputs each, Ni1000 and 0...10 VDC
Description
The RIO module was developed as a S-Bus data node for local switching tasks. Via a DDC of the type PCDx / PCS1 temperatures of -50°C to 150°C and/or voltages
of 0...10 VDC can be read. Two address switches (×1 / ×10) on the front panel allow module addressing and identification. Addresses can be set between 00 and 99.
Up to 100 RIO modules and a maximum of 3 PCD stations can be connected to one bus branch simultaneously. If the bus cycle time is critical, fewer than 30 slaves should be
operated in one segment.

Joined without spacing
After 15 modules have been joined in
sequence or a maximum supply current of 2 A (AC or DC)
per port on the powersupply, the external supply voltage must be reapplied.
Data transmission
All S-Bus instructions (level 1) are recognized. Instructions that have no function in the device are answered with <NAK>. The module has integral, automatic baud rate and
transmission mode recognition.

Bus timer (register 8)
The value displayed indicates how long the module waits until a telegram is complete. The time is shown in 10 ms steps (e.g.: value 20 => a time of 200 ms). The recommended
time is 100 ms, i.e. a register value of 10. If the time is reduced, modules will react faster to telegrams from the master. If there is a heavy load on the master station, a bus timer
setting that is too low may lead to lost telegrams. Times of less than 20 ms (value 2) are not permitted.
Times that reach the master station within 20 ms of the timeout will lead to lost connections. The value is stored in EEPROM and protected against voltage loss. ( Factory setting : 2)

"Write Output"
The write output instruction at address 255 is recognized as broadcast message.
Automatic baud function: "Write or Display output 255" (1 = autobaud active / 0 = autobaud inactive)
N.B:
After a power failure, the last baud rate set will be reinstalled.
The autobaud function must not be turned on permanently, but only on the commisioning. At the condition as
supplied to the customer, the autobaud is turned on, to adjust the device automatically to the system. But after the
commisioning it has to be switched-off via bus command.
For further information on the use of modules linked to S-Bus, including all restrictions,
see documentation 26/339 EN

1= Last transmission was a broadcast
0= Last transmission was not a broadcast
1= Last transmission came from master
0= Last transmission came from a slave
1= CRC of last message was correct
0= CRC of last message was incorrect
1= Device has executed an internal reset
0= Device function is OK
1= Internal bus to EEPROM is OK
0= Internal bus not working perfectly

Place module onto 35 mm tophat rail and press
down to engage.
3.

lines and supply.
Operational safety:
Please take care to following points
for a safety operation:
- Maximal cable length
- S-Bus member and segment
division
- Potential compensation by one
single grounding of power supply
- Termination of both network sides
- Cable shield grounding on one
side only.
