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

Examples:

VM parameter = 108

VM parameter = 2145

VM parameter = 0

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

VM 1014

VM 1016

VM 1015

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.”)
