The communication example illustrates communication for the commented monitoring on
the RS232 link between unit SEP (A) and the CU, the sending of packets through the
MORSE network during a change on the binary inputs BI, receipt of a MORSE packet by
the target CU and final communication over RS232 between the CU and unit SEP (B).
SEP-A - transmitting:
Messages which are marked here with time 08:45:45 to 08:45:47 repeat with a period
(p)oll and transmit information over the SCC about the state of sensors, commands
for setting outputs and a message about the state of inputs. If an input change is
registered a MORSE packet (08:45:47) is transmitted and the exchange of information
over SCC continues.
SEP-B - receipt:
After receiving a MORSE packet (08:45:47) information about the state of inputs BI,
AI0,AI1 is received from SEP-A inserted into the nearest cycle on the SCC
(08:45:48.430) as a command for setting BO, AO0, A01 to SEP-B. Information about
the state of counters in SEP-A is not transmitted to SEP-B. It can only be used in
applications which may be connected.
For transparency long rows of monitoring are shortened in such a way that data of
counters C6, C7 are removed on the physical channel and C1 to C7 on the CNI.
SEP A - transmitting

change in content of counter C0 entry of =BO into SEP B
Notes on monitoring:
1) Period (p)oll is set here to 1000ms for easier monitoring, normally 100 to 300ms
are used.
2) The value of counters on SCC (SEP-A row 08:45:46.016) has an inverse order of
bytes, see (08:45:47.029). The counter increments by the rising edge of BI.
3) State AI indicated by value FFFE (08:45:47.029), for example, arises when an
input is disconnected due to the influence of negative calibration constant
(l)ower.
4) Value AI0 = 0x21F5 (SEP-A 08:45:47.018) is transmitted and inserted into SEP-B
(08:45:48.430) in the physical unit dimensions (here 0 to 20000 uA, i.e. 0 to
0x4E20). It is converted there according to the calibration constant to converter
units (0 to 0xFFF) and inserted into the D/A converter AO0.
Upon the next AO0 status request in SEP-B (08:45:48.475) the physical value AO0 is
measured through the separate input AI9 with the result in the A/D converter range
(0 to 0xFFF) converted to a physical dimension (0 to 0x4E20) and sent to the CU,
here as AO0 = 0x21EC.
These essential rounding errors are given by the comfort of communication with the
user in physical units. We see that in the case of a neighbouring channel AI1,
AO1, AI10, which have calibration constants set here to the range 0 to 0xFFF, i.e.
0 to 4095, alteration of the transmitted value 0x0013 doesn't occur here.
5) SEP protocol parameters used in the example:
CU 690F5505 and SEP-A:
SEP parameters:
p(a)rtner:690F5606h t(i)me:0s (p)oll:100*10 ms
(t)hr:250 (c)thr:1 (f)ilter:0 (m)ask:FFh
(e)rr:SILENCE (v)er:SEP 1.03
(G)roup mode:OFF
SEP-A had inputs BI6, BI7 on. During entry BI0 was on briefly. A current of 9mA
was fed to AI0
CU 690F5606 a SEP-B:
SEP parameters:
p(a)rtner:690F5505h t(i)me:0s (p)oll:100*10 ms
(t)hr:250 (c)thr:1 (f)ilter:0 (m)ask:FFh
(e)rr:SILENCE (v)er:SEP 1.03
(G)roup mode:OFF
SEP-B had input BI7 switched on

In the central CU
this information is stored in cache memory of the Modbus protocol from where it is
read by the Master PLC. We can monitor the state of cache using commands "mp0M".

The length of cache is defined in the Art table related to the Modbus protocol in
the CU 691122FF, see the description of the Modbus protocol. In the example the
following are in Art:
dest: gw:
0000001E 00010000
Cache created in this way has a length of 1 word and stores it with the first 2
bytes of the content of the SEP packet. The length of cache is selectable, e.g. for
storing the whole packet:
dest: gw:
0000001E 001C0000
Cache then looks as follows:
