SyMax Class 8020 Model 300
The Symax Model 300 error codes will display on a connected CRT screen.
|Error code|| Description|
|01||Illegal protocol opcode, the SY/MAX device does not recognize the instruction|
|02||Illegal intermediate code format.|
|03||An illegal address has been attempted.SY/MAX device does not contain the requested register(s).|
|04||Illegal rack addressing has been attempted.|
Attempt was made to incorrectly edit rack addressing
|05||1. An instruction has been attempted which is not supported in this type processor|
(Example: square root calculation attempted in Model 300 processor.)
2. Incorrect mode set for NIM port connected to a processor (receiving device). Mode set for 8881 mode or peripheral mode.
3. In a Nel-to-Net link, the two NIMs have different address settings (on thumb-wheels), or link is between ‘0’ port on one and ‘l’ port on the other.
|06||Unable to find the searched-for item.|
|07||An attempt has been made to alter data in a protected register|
|08||An attempt has been made to access protected memory|
|09||An attempt has been made to alter data in a READ ONLY register or a register containing external inputs|
|10||An attempt has been made to exceed memory limitations|
|11||Communication Error. Sy/Max Device went into an overflow condition|
|12||Illegal CPU rack addressing. Attempted rack address is incompatible with processor hardware|
|13||Communications error (link error.)|
|14||Operation not allowed to run.|
|16||The register count in a communication rung is too large for the processor.|
|17||Unable to establish communications to remote Sy/Max Device.|
|18||The rung number used is not allowed|
|19||An illegal READ parameter has been assigned|
|20||Channel number in a communication rung is too large for the processor.|
SyMax 8020 Model 400
The Symax Model 400 makes use of an enhanced print rung format allowing the user to input ASCII-coded data. Error codes typically appear within the Status Register.
|11||The model is not capable of properly handle incoming |
characters due to demands from other interrupts
|15||Framing error, typically caused by word structure issues or |
|17||Termination occurred before full ASCII string was received. |
The results from the CPU going to halt, or bit 16 of Register
8099/8100 being set. If the latter, the buffers in line for ASCII
input are cleared
|19||Buffer overflow. The 256 character buffer was filled before|
the terminating character was received.
