4.4.5.1. Set a message without variables.
When you want to set a message without variables, you should put the Message
Number into a free place on the VM table, between positions VM n and VM n+5. If more than
one message is set, the position into the table is used to control the order in which messages
will be displayed.
4.4.5.2. Reset a message without variables.
To reset messages without variables, you must set its position on the table to 0
orchange the message number for the other message number

4.4.5.3. Set a message with variables.
When you want to set a message with variables, you should put the Message Number
into a free place on the DM table, between positions VM n+6 and VM n+9. If more than one
message is set, the position into the table is used to control the order in which messages will be
displayed.
Using Messages with variables, besides the message number, you must program the
position where the variable will be found inside the PLC. Programm the position and the VM
number from VM n+20 to VM n+34. Every one of the four messages with variables has 2 VM’s
for variable data. These 2 VM’s work as indirect addressing, first VM has the address where the
data is located while the second VM has the number of VM used.
Example.
VM parameter = 1000
VM 1012
0
VM 1014
25
VM 1016
0
VM 1015
0
VM 1012 = 25 Set message 25.
VM 1025 = The variable dara are located at VM 500.
VW 1026 = 9 9 VB’s from VW 500 to VB 508. Use VW or VB not significant, but
remember that a VW occupies two VB’s.
VW 500 a VW 506 = Variable data. ( See 4.4.5.6 “Data variables.”)
