MODCELL SERIAL COMMUNICATION BLOCK
4-32
70-74 Multiple Register Read/Write List 1 - 5 (MRWLISTn).....................................................C – R
These values represent configured lists which make up the multiple read/write register for the
lists (1 through 5) for this Modbus port. List 1 has a memory range of (41001 - 41999); list 2
has a memory range of (42001 - 42999); list 3 has a memory range of (43001 - 43999); list 4
has a memory range of (44001 - 44999); and list 5 has a memory range of (45001 - 45999).
The selected configured list must be configured, have a buffer allocated, and not have any
nested lists.
NONE No configured list. Read as 0.
CL10 to CL4096 The number of the Configured List (CL) block that makes up the
multiple read/write register list for this Modbus port. Read as the
number of the Configured List (10 to 4096).
74-79 Multiple Register Read Only List 1 - 5 (MROLISTn) ......................................................C – R
These values represent configured lists which make up the multiple read only register for the
lists (1 through 5) for this Modbus port. List 1 has a memory range of (31001 - 31999); list 2
has a memory range of (32001 - 32999); list 3 has a memory range of (33001 - 33999); list 4
has a memory range of (34001 - 34999); and list 5 has a memory range of (35001 - 35999).
The selected configured list must be configured, have a buffer allocated, and not have any
nested lists.
NONE No configured list. Read as 0.
CL10 to CL4096 The number of the Configured List (CL) block that makes up the
multiple read only register list for this Modbus port. Read as the
number of the Configured List (10 to 4096).
80 Module Type (COMMTYPE) ..............................................................................................C – R
This value represents the type of hardware used for communications. The modules with
address switches require a corresponding MSC block for the instrument to run and prevent a
port mismatch (if no data base is present, a default MSC block is created with a default
communication setup of 9600 baud, no parity, 1 stop bit and slave functionality). Valid
hardware types are:
RS232 (2031N) 0 RS232 communications.
RS485 (2032N) 1 Single slot RS485 communications.
RS232 (2033N) 5 Double slot RS232 communications with Address.
RS485 (2034N) 6 Double slot RS485 communications with Address.
81 Command (CMD) ...............................................................................................................– WR
This field provides a dummy location in the database to which commands can be addressed
using a long state variable. The value read from this location is always 0. The following
values, when written to this location are interpreted as commands:
1 RESET DIAG. COUNTERS - resets all the diagnostic counters to 0.
2 INITIALIZE SERIAL PORT - re-initializes the serial port associated
with this block. Version 2 of this block requires that this value be
written after a communication parameter is changed with a write
message to the database.
251 BE A MODBUS MASTER - re-initializes the serial port associated
with this block to be a Modbus Master.
252 BE A MODBUS SLAVE - re-initializes the serial port associated with
this block to be a Modbus Slave.
