Bad Declaration, use %MX for 'BOOL' variable

[seikosantana]

Hello, I am using Machine Expert 1.2.7 to program a TM241 PLC.

I am having trouble assigning an address (Modbus register) to a variable of type BOOL because at certain times, using the address %MX causes the variable to become a BIT type.

I need to keep using BOOL because I need to use the variable as an IN_OUT variable for a function block.

If I use MB or MW for the address in the declaration, during compilation, I get a "Bad Declaration, use %MX for 'BOOL' variable" error. Is there another way to assign the address and maintain the type as BOOL and not BIT?

Thank you.

Did you try to use %MWx.y instead of %MXx ?

I am also using ESME V1.2.

I declare the variable like below.

--------------------------------------------

{attribute 'qualified_only'}
VAR_GLOBAL
xG_mccbAl AT %MX2000.0: BOOL;
xG_elbAl1 AT %MX2002.0: BOOL;
xG_elbAl2 AT %MX2002.1: BOOL;
xG_elbAl3 AT %MX2002.2: BOOL;
xG_elbAl4 AT %MX2002.3: BOOL;
xG_elbAl5 AT %MX2002.4: BOOL;
xG_elbAl6 AT %MX2002.5: BOOL;
END_VAR
